PURPOSE:To achieve an audio output control system without losing the simplicity of connection system, by synchronizing the operation by the operation with the audio output of the system. CONSTITUTION:When an instruction comes via a system bus externally, a transmission/reception section 14 transmits the reception of the code to a processor unit 11. The unit 11 moves the execution of the firmware in a ROM12 to the start. The unit 11 reads in said code and when the code is not a status read- in code, the output of audio corresponding to said code is instructed. If the code is a status read-in code, the transmission/reception section 14 is made possible for transmission to read the state (if in operation or not) of an audio synthesis section 15 and the state is set to the section 14. An external device receives a signal from the section 14, and if this does not shown in-operation, the audio output code is transmitted and the audio is immediately outputted. |
