In particular, in a telephone device connected to a telephone line, a so-called parent-child telephone in which one parent device (= main device) and a plurality of child devices share a telephone line is widely used.

  One of the functions of the parent / child phone is a hands-free function (= hand-on call function). The hands-free function is a function of amplifying sound by a power amplifier and outputting from the speaker when the slave unit outputs sound from the speaker. Thus, the user can make a call without holding the handset (= hands-free state), for example, with the handset placed on the table.

  Functions using this hands-free function include an extension voice call function and an absence monitor function. With the extension voice call function, when a request for extension communication is generated from the master unit to the slave unit, the slave unit makes a request response without requiring a user operation. This automatically shifts to the call state. In this call state, the hands-free function is effective. For this reason, it is possible to make a call even if the handset is located away from the user.

  Also, the answering machine monitoring function detects when an incoming call is detected from the telephone line, and when the phone changes to the answering machine mode in which the other party is notified that the call is being recorded and the call contents can be recorded. This is a function for outputting the audio output from the speaker using the hands-free function of the slave unit. As a result, the user can listen to the voice guidance of the answering machine function or the voice received by the master unit in a hands-free state from the speaker of the slave unit.

  However, when using the above-mentioned hands-free function or various functions using the hands-free function, the output volume is greatly amplified by the power amplifier of the slave unit, so it is more than the call processing with the normal master unit. Consume power. For this reason, the burden on the battery of the slave unit increases, and the user must frequently charge the battery of the slave unit. If charging is neglected, there is a possibility that the slave unit may cause various malfunctions due to insufficient battery power, for example, problems such as difficulty in hearing voice in a call state.

  In relation to the above, Patent Document 1 discloses a convenience for a user by resuming a hands-free call using another mobile phone even when the mobile phone that is performing the call processing becomes unable to communicate. A hands-free telephone device that can improve performance is disclosed.

The hands-free telephone device of Patent Document 1 enables a hands-free call using a mobile phone by performing short-range wireless communication with the mobile phone. The hands-free telephone device includes short-range wireless communication means for performing short-range wireless communication with a plurality of mobile phones. The short-range wireless communication means receives and stores battery remaining amount information indicating the remaining battery amount of each of the plurality of mobile telephones. Then, when it is detected that the remaining battery level of the mobile phone that is performing a call process with another telephone device among a plurality of mobile phones has decreased to a predetermined value or less, the call process is performed. The short-range wireless communication means is controlled so as to perform short-range wireless communication with another mobile phone having a remaining battery level higher than the mobile phone being performed. Thereby, it is possible to switch the mobile telephone which performs a telephone call process between other telephone apparatuses.

As a result, the wireless communication unit 24 transmits a communication request to the parent device 1. Further, it has a role of notifying the control unit 21 when a communication request from the parent device 1 is received.

  The audio signal processing unit 25 decodes the audio data input by the wireless communication unit 16 and supplies the audio data to the speaker 26 via the power amplifier 27 as an audio signal. The audio signal processing unit 25 performs predetermined encoding processing on the audio signal input from the microphone 30 to generate audio data, and supplies the audio data to the wireless communication unit 16. As a result, the audio data is transmitted to the parent device 1 or another telephone device connected by the parent device 1 through a telephone line.

  The speaker 26 converts the sound signal into sound and outputs it. For example, a voice signal including a call voice received from the base unit 1 is converted into a voice and output. The power amplifier 27 amplifies the sound volume when the speaker 26 outputs sound. If the power amplifier 27 is used, it is possible to amplify the sound so that it can be heard even when the handset 2 is not close to the user's ear and output the sound.

  The operation button group 28 is used for the user to perform various operations (for example, input of the telephone number of the other party to perform a call) for performing communication using the handset 2. The operation button group 28 is generally composed of a plurality of keys such as numeric keys and redial keys. The display unit 29 displays various types of information (for example, notification of extension incoming calls) held by the handset 2 to the user. As the display unit 29, for example, a small and low power consumption display device such as a liquid crystal panel is often used.

  The microphone 30 inputs voice, converts it into a voice signal, and gives it to the voice signal processing unit 25. The audio signal given to the audio signal processing unit 25 is transmitted to the base unit 1 using, for example, the wireless communication unit 24 and the antenna device 23. The battery 31 is supplied with electric power from an external power source (not shown) and temporarily stores the electric power. For example, a rechargeable alkaline battery or a lithium ion battery is used.

<1-3. About the configuration of the function section>
Here, the relationship of each function part which comprises the operation | movement prohibition process of the hands-free function with which the subunit | mobile_unit 2 which concerns on 1st embodiment of this invention is provided is demonstrated, using the functional block diagram of FIG.

  As shown in FIG. 3, the operation prohibiting process of the hands-free function of the present invention includes at least a remaining capacity confirmation unit 21a, a remaining capacity determination unit 21b, an operation prohibiting unit 21c, a hands-free function unit 21d, An amplifier 27 and a battery 31 are included.

  The remaining capacity confirmation unit 21a periodically confirms the remaining capacity of the electric power stored in the battery 31. The confirmation result is given to the remaining capacity determination unit 21b. The remaining capacity determination unit 21b, which is provided with the confirmation result of the remaining battery capacity from the remaining capacity confirmation unit 21a, determines whether or not the remaining capacity is lower than a predetermined value. As a standard for determining the predetermined value, it is desirable that the slave unit 2 has a capacity that allows other functions other than the hands-free function, such as a call function and a communication request transmission / reception function, to be performed without any trouble.

  When it is determined that the remaining capacity is less than the predetermined value, the remaining capacity determination unit 21b sets the remaining capacity shortage flag recorded in the memory 22 to the valid state. Conversely, when it is determined that the remaining capacity is exceeded, the remaining capacity shortage flag recorded in the memory 22 is set to an invalid state. The remaining capacity shortage flag is referred to by the operation prohibiting unit 21c when a hands-free call is performed by the hands-free function unit 21d.

  The operation prohibiting unit 21c checks the state of the remaining capacity shortage flag recorded in the memory 22, and prohibits the operation of the hands-free function unit 21d when the remaining capacity shortage flag is set to the valid state. As a result, the hands-free function unit 21d does not instruct the power amplifier 27 to amplify the output voice even when, for example, a hands-free call request is received from the master unit. The hands-free function unit 21d can give a sound amplification instruction to the power amplifier 27 as usual when the operation prohibition instruction from the operation prohibition unit 21c is released.

<1-4. Operation prohibition processing for hands-free function>
Here, the operation prohibiting process of the hands-free function of the handset 2 in the first embodiment of the present invention will be described with reference to the block diagrams of FIGS. 1 to 3 and the flowchart of FIG.

  The processing flow shown in FIG. 4 can be started at an arbitrary timing in a state where the power of the slave unit 2 is activated and communication with the master unit 1 is possible. After the start of this process, the remaining capacity confirmation unit 21a confirms the remaining capacity of the electric power stored in the battery 31 in step S110. The confirmation result is given to the remaining capacity determination unit 21b. The remaining capacity determination unit 21b given the confirmation result determines whether or not the remaining capacity of the battery 31 falls below a predetermined value in step S120.

  If it is determined in step S120 that it is below the predetermined value, the remaining capacity determination unit 21b checks the state of the remaining capacity shortage flag recorded in the memory 22 in step S130. If the remaining capacity shortage flag is set to invalid, the remaining capacity determination unit 21b sets the remaining capacity shortage flag to be valid in step S140. If the remaining capacity shortage flag is set to invalid, the process proceeds to step S150 described later without performing the process of step S140.

  Conversely, when it is determined in step S120 that the predetermined value is exceeded, the remaining capacity determination unit 21b checks the state of the remaining capacity shortage flag recorded in the memory 22 in step S121. If the remaining capacity shortage flag is set to be valid, the remaining capacity determination unit 21b sets the remaining capacity shortage flag to be invalid in step S122. If the remaining capacity shortage flag is set to invalid, the process proceeds to the next step S150 without performing the process of step S122.

  In step S150, the control unit 21 determines whether an execution command for the hands-free call function is detected. The execution instruction for the hands-free call function is issued, for example, when the extension call connection is established between the slave unit 2 and the master unit 1 and the hands-free call function is enabled by the setting on the slave unit. Is done. If the execution command for the hands-free call function is not detected, the process proceeds to step S110 again.

  On the contrary, when the execution instruction of the hands-free call function is detected in step S150, the operation prohibiting means 21c checks the state of the remaining capacity shortage flag recorded in the memory 22 in step S160. When the remaining capacity shortage flag is set to be valid, the operation prohibiting unit 21c gives an operation prohibiting instruction to the hands-free function unit 21c in step S170. As a result, the hands-free function unit 21c cannot perform the hands-free function, for example, a voice amplification instruction to the power amplifier 27. For this reason, normal volume sound is output from the speaker 26. In addition, after execution of step S170, this process is continued by moving to step S110 again.

  On the contrary, when the remaining capacity shortage flag is set to invalid, the hands-free function unit 21c performs the hands-free function, for example, instructs the power amplifier 27 to amplify the sound in step 161. For this reason, a sound whose volume is amplified is output from the speaker 26. In addition, after implementation of step S161, this process is continued by moving to step S110 again.

  As described above, this processing is normally terminated when the power of the slave unit 2 is stopped or when the battery runs out. However, it may be configured such that the processing can be interrupted at an arbitrary timing by providing an instruction receiving unit that receives a processing interruption instruction.

Next, a second embodiment of the telephone device of the present invention will be described with reference to the drawings.

Since it is the same content as Embodiment 1, description is abbreviate | omitted here.

<2-3. About the configuration of the function section>
Here, the relationship between the functional units constituting the operation prohibition process of the extension voice call function provided in the handset 2 according to the second embodiment of the present invention will be described with reference to the functional block diagram of FIG. In addition, about the function part of the same content as Embodiment 1, description shall be abbreviate | omitted by adding the same code | symbol.

  As shown in FIG. 5, at least the remaining capacity confirmation unit 21a, the remaining capacity determination unit 21b, the remaining capacity notification unit 21d, and the extension voice call function unit 21e included in the control unit 21 are included in the operation prohibition process of the extension voice call function of the present invention. And a wireless communication unit 24, a power amplifier 27, and a battery 31.

  Since the remaining capacity confirmation unit 21a and the remaining capacity determination unit 21b have the same contents as those of the first embodiment, description thereof will be omitted.

  The remaining capacity notifying unit 21d transmits a remaining capacity shortage flag state change notification to the base unit 1 using the wireless communication unit 24 when the remaining capacity determining unit 21b changes the state of the remaining capacity insufficient flag. . At this time, it is desirable that information indicating the remaining capacity of the battery 31 is also transmitted. The information transmitted by the remaining capacity notifying unit 21d is received by the wireless communication unit 16 of the parent device 1 and recorded in the memory 12.

  When the extension voice call function unit 21e receives an extension call request from the base unit 1, the extension voice call function unit 21e automatically responds to the extension call request without requiring a user operation, and further amplifies the output voice to the power amplifier 27. Instruct. The extension voice call function unit 21 operates only when the extension voice call function is enabled in advance by user settings. The valid / invalid setting is recorded, for example, in the memory 22 of the slave unit 2. Alternatively, the extension voice call function unit 21e may be operated only when an execution command for the extension voice call function is sent together with the extension call request from the master unit.

<2-4. Extension prohibition voice call function>
Here, the operation prohibition processing of the extension voice call function of the master unit 1 and the slave unit 2 in the second embodiment of the present invention is shown in the block diagrams of FIGS. 1, 2, and 5, FIG. 6, and FIG. This will be described with reference to the flowchart of FIG. 6 shows the processing flow of the child device 2, and FIG. 7 shows the processing flow of the parent device 1.

  The processing flow of the slave unit 2 shown in FIG. 6 can be started at an arbitrary timing in a state where the power source of the slave unit 2 is activated and communication with the master unit 1 is possible. After the start of this process, the remaining capacity confirmation unit 21a confirms the remaining capacity of the electric power stored in the battery 31 in step S210. The confirmation result is given to the remaining capacity determination unit 21b. The remaining capacity determination unit 21b given the confirmation result determines whether or not the remaining capacity of the battery 31 falls below a predetermined value in step S220.

  If it is determined in step S220 that the value is below the predetermined value, the remaining capacity determination unit 21b checks the state of the remaining capacity shortage flag recorded in the memory 22 in step S230. If the remaining capacity shortage flag is not set to invalid, that is, it is valid, the process is continued by moving again to step S210. Conversely, when the remaining capacity shortage flag is set to invalid, the remaining capacity determination unit 21b sets the remaining capacity shortage flag to be valid in step S240.

  Next, in step S250, the remaining capacity notifying unit 21d transmits information indicating the changed remaining capacity flag, in this case, information indicating that the flag is valid, to the base unit 1 using the wireless communication unit 24. . After transmitting the flag information, the process is continued by moving again to step S210.

  Conversely, when it is determined in step S220 that the predetermined value is exceeded, the remaining capacity determination unit 21b checks the state of the remaining capacity shortage flag recorded in the memory 22 in step S221. If the remaining capacity shortage flag is set to invalid, the process is continued by moving to step S210 again. Conversely, when the remaining capacity shortage flag is set to be valid, the remaining capacity determination unit 21b sets the remaining capacity shortage flag to be invalid in step S222.

  Next, in step S250, the remaining capacity notifying unit 21d transmits information indicating the changed remaining capacity flag, in this case, indicating that the flag is invalid, to the base unit 1 using the wireless communication unit 24. . After transmitting the flag information, the process is continued by moving again to step S210.

  As described above, this processing is normally terminated when the power of the slave unit 2 is stopped or when the battery runs out. However, it may be configured such that the processing can be interrupted at an arbitrary timing by providing an instruction receiving unit that receives a processing interruption instruction.

  Next, the processing flow of the parent device 1 that has received the flag information transmitted in step S250 of the child device 2 will be described with reference to FIG. The processing flow of the master unit 1 shown in FIG. 7 can be started at an arbitrary timing in a state where the power source of the master unit 1 is activated and communication with the slave unit 2 is possible.

  After the start of this process, the control unit 11 determines whether or not the wireless communication unit 16 has received flag information indicating the remaining battery capacity of the child device 2 in step S310. When the flag information is received, the control unit 11 records the received flag information in the memory 12 in step S320. Conversely, if flag information has not been received, step S320 is not performed, and the process proceeds to the next step S330.

  In step S330, the control unit 11 determines whether an execution command for the extension voice call function is detected. The execution command for the extension voice call function is, for example, that an extension call request is transmitted from the master unit 1 to the slave unit 2, and the extension voice call function is set to be effective by the setting on the master unit side (or the slave unit side). Issued if If the control unit 11 has not detected the execution command for the extension voice call function, the process proceeds to step S310 and the present process is continued.

  Conversely, when the control unit 11 detects an execution command for the extension voice call function in step S330, the control unit 11 reads the flag information of the slave unit 2 recorded in the memory 12 in step S340. Then, based on the validity / invalidity of the remaining capacity shortage flag included in the read flag information, it is determined in step S350 whether the remaining capacity shortage flag is valid, that is, whether the remaining capacity of the battery 31 of the child device 2 is in a shortage state. I do.

  If it is determined in step S350 that the remaining capacity shortage flag is valid, in step S360, the control unit 11 prohibits execution of processing related to the implementation of the extension voice call function for each unit included in the parent device 1. Specifically, for example, the control unit 11 instructs the wireless communication unit 16 to prohibit the request signal for requesting the slave unit 2 to execute the extension voice call function.

  As a result, the wireless communication unit 16 can transmit only a normal extension call request even when, for example, the extension voice call function is enabled and an extension call occurs. As a result, a normal extension call without using the extension voice call function is performed, and the power amplifier 27 of the slave unit 2 does not amplify the output voice. In addition, after execution of step S360, this process is continued by moving to step S310 again.

  Conversely, if it is determined in step S350 that the remaining capacity shortage flag is invalid, the control unit 11 performs a normal extension voice call function execution process in step S351. In addition, after implementation of step S351, this process is continued by moving to step S310 again.

  As described above, this processing is normally terminated when the power of the base unit 1 is stopped or when the battery runs out. However, it may be configured such that the processing can be interrupted at an arbitrary timing by providing an instruction receiving unit that receives a processing interruption instruction.

Next, a third embodiment of the telephone device of the present invention will be described with reference to the drawings.

Since it is the same content as Embodiment 1, description is abbreviate | omitted here.

<3-3. About the configuration of the function section>
Here, the relationship of each function part which comprises the operation prohibition process of the answering machine monitor function with which the subunit | mobile_unit 2 which concerns on 3rd embodiment of this invention is provided is demonstrated, using the functional block diagram of FIG. In addition, about the function part of the same content as Embodiment 1, description shall be abbreviate | omitted by adding the same code | symbol.

  As shown in FIG. 8, the operation prohibiting process of the answering machine monitor function of the present invention includes at least a remaining capacity confirmation unit 21a, a remaining capacity determination unit 21b, a communication function unit 21f, and an answering machine monitor unit 21g provided in the control unit 21. The wireless communication unit 24, the power amplifier 27, and the battery 31 are included.

  Since the remaining capacity confirmation unit 21a and the remaining capacity determination unit 21b have the same contents as those of the first embodiment, description thereof will be omitted.

  The communication function unit 21 f uses the wireless communication unit 24 to control wireless communication performed with the wireless communication unit 16 of the parent device 1. For example, when an extension call request issued from the wireless communication unit 16 is received, a request is returned to the wireless communication unit 16. Further, for example, when the wireless communication unit 16 is notified that the base unit 1 has detected an external line incoming call, external line incoming call processing relayed through the base unit, for example, output of a ringtone by the speaker 26 or external line incoming information by the display unit 29 Instructions such as display are performed. Also, for example, when receiving an execution instruction for the answering machine monitoring function from the base unit 1, it has a role of giving an operation instruction to an answering machine monitoring unit to be described later.

  The answering machine monitor unit 21g uses the wireless communication unit 24 to receive the voice of the call by the outside line communication and the guidance voice output by the parent machine 1 when the master unit 1 receives the outside line and shifts to the answering machine mode. The volume is amplified using the power amplifier 27 and output from the speaker 26. Note that the answering machine monitor function unit 21 operates only when the answering machine monitor function is enabled in advance by user settings. The valid / invalid setting is recorded, for example, in the memory 22 of the slave unit 2. Alternatively, the answering machine monitoring unit 21g may be operated only when the execution instruction of the answering machine monitoring function is sent from the parent machine together with the notification of transition to the answering machine mode.

<3-4. About the operation prohibition processing of the answering machine monitor function>
Here, the operation prohibition processing of the answering machine monitoring function of the master unit 1 and the slave unit 2 in the third embodiment of the present invention is shown in the block diagrams of FIGS. 1, 2, and 8, FIG. 9, and FIG. This will be described with reference to FIG. 9 shows the processing flow of the slave unit 2, and FIG. 10 shows the processing flow of the master unit 1.

  The processing flow of the slave unit 2 shown in FIG. 9 can be started at an arbitrary timing in a state where the power source of the slave unit 2 is activated and communication with the master unit 1 is possible. After the start of this process, the remaining capacity confirmation unit 21a confirms the remaining capacity of the electric power stored in the battery 31 in step S410. The confirmation result is given to the remaining capacity determination unit 21b. In step S420, the remaining capacity determination unit 21b given the confirmation result determines whether the remaining capacity of the battery 31 is below a predetermined value.

  If it is determined in step S420 that it is below the predetermined value, the remaining capacity determination unit 21b checks the state of the remaining capacity shortage flag recorded in the memory 22 in step S430. If the remaining capacity shortage flag is not set to invalid, that is, it is valid, the process proceeds to step S450 described later. Conversely, when the remaining capacity shortage flag is set to invalid, the remaining capacity determination unit 21b sets the remaining capacity shortage flag to be valid in step S440.

  Conversely, when it is determined in step S420 that the predetermined value is exceeded, the remaining capacity determination unit 21b checks the state of the remaining capacity shortage flag recorded in the memory 22 in step S421. If the remaining capacity shortage flag is set to invalid, the process proceeds to step S450 described later. Conversely, when the remaining capacity shortage flag is set to be valid, the remaining capacity determination unit 21b sets the remaining capacity shortage flag to be invalid in step S422.

  Next, in step S450, the communication function unit 21f confirms whether or not the wireless communication unit 24 has received any communication request from the parent device 1, such as an extension call request. If a communication request is not detected, the process is continued by moving to step S410 again. On the other hand, when a communication request is detected, the communication function unit 21f embeds and transmits flag information indicating the state of the remaining capacity shortage flag of the battery 31 in a reply signal to the communication request in step S450.

  When embedding flag information in a reply signal, it is desirable to embed flag information in a reserved area or the like that is unused in the specification in the reply signal. The reply signal in which the flag information is embedded by the communication function unit 21 f is sent from the wireless communication unit 24 to the base unit 1. Thereafter, the process is continued by moving again to step S410.

  As described above, this processing is normally terminated when the power of the slave unit 2 is stopped or when the battery runs out. However, it may be configured such that the processing can be interrupted at an arbitrary timing by providing an instruction receiving unit that receives a processing interruption instruction.

  Next, the processing flow of base unit 1 will be described with reference to FIG. The processing flow of the parent device 1 shown in FIG. 10 can be started at an arbitrary timing in a state where the power of the parent device 1 is activated and communication with the child device 2 is possible.

  After the start of this process, in step S510, the control unit 11 determines whether an instruction to issue a communication request for communicating with the slave unit 2 is received using the wireless communication unit 16. The communication request issuance instruction is issued, for example, when the user performs a dial operation for starting an extension call with the handset 2 using the operation button group 18.

  If the control unit 11 has not detected an instruction to issue a communication request, the process proceeds to step S530 described later. On the other hand, when the communication request issuance instruction is detected, the control unit 11 transmits the communication request to the slave unit 2 using the wireless communication unit 16 and waits for a reply. In response to this communication request, the reply process of the slave unit 2 is performed in steps S450 and S460 of FIG. Upon receiving the reply, the control unit 11 of the base unit 1 extracts flag information indicating the remaining battery capacity from the reply signal and records it in the memory 12 in step S520.

  The data format of flag information included in the reply signal and the recording area inside the reply signal are determined in advance between the master unit 1 and the slave unit 2 and recorded on a recording medium such as a ROM (not shown). ing. Further, when a reply is not obtained from the handset 2 due to communication failure or the like, or when the flag information is not included in the reply, the flag information is not recorded in the memory 12.

  Next, in step S530, the control unit 11 determines whether or not an execution instruction for the answering machine monitoring function has been detected. The execution instruction of the answering machine monitor function is such that, for example, the telephone line control unit 13 of the master unit 1 detects an incoming incoming call, shifts to the answering machine mode, and the answering machine monitor function is enabled by the setting of the master unit 1. Issued if When the control unit 11 does not detect the execution instruction of the answering machine monitoring function in step S530, the process proceeds to step S510 again to continue this process.

  On the other hand, when the control unit 11 detects an execution instruction for the answering machine monitoring function in step S530, the control unit 11 reads the flag information of the slave unit 2 recorded in the memory 12 in step S540. Then, based on the validity / invalidity of the remaining capacity shortage flag included in the read flag information, it is determined in step S550 whether the remaining capacity shortage flag is valid, that is, whether the remaining capacity of the battery 31 of the child device 2 is in a shortage state. I do.

  If it is determined in step S550 that the remaining capacity shortage flag is valid, in step S560, the control unit 11 prohibits each unit included in the base unit 1 from executing processing related to the implementation of the answering machine monitoring function. Specifically, for example, the control unit 11 prohibits the wireless communication unit 16 from transmitting an external line voice or guidance voice to the handset 2 by the answering machine monitor function. Alternatively, the transmission start request for the answering machine monitoring function to the handset 2 may be prohibited.

  Thereby, for example, even when the base unit 1 detects an incoming incoming call and shifts to the answering machine mode, and the answering machine monitoring function is set to be effective, the wireless communication unit 16 can communicate with the handset 2. Do not perform communication related to the answering machine monitor function. As a result, the main unit 1 performs external line call voice recording processing by the answering machine function, but the slave unit 2 does not perform external line call voice output processing using the speaker 26 and the power amplifier 27.

  Of the processes included in the answering machine monitor function, processes other than the voice output process by the speaker 26 and the power amplifier 27, for example, character information indicating that the master unit 1 is currently in the answering machine mode are displayed on the display unit of the slave unit 2 The process etc. performed to 29 may be an embodiment. In addition, after execution of step S560, the process is continued by moving to step S510 again.

  On the other hand, if it is determined in step S550 that the remaining capacity shortage flag is invalid, the control unit 11 performs a normal answering machine monitor function execution process in step S551. Note that after step S551 is performed, the process is continued by moving to step S510 again.

  As described above, this processing is normally terminated when the power of the base unit 1 is stopped or when the battery runs out. However, it may be configured such that the processing can be interrupted at an arbitrary timing by providing an instruction receiving unit that receives a processing interruption instruction.
