Abstract

PURPOSE:To lower the cost per circuit as well as to lessen the load of the hardware for the synchronous-type multi-circuit communication control unit by providing the ACU (arithmetic unit) which is changed into the firmware. CONSTITUTION:At the transmission time, CPU1 sets the circuit number and the data necessary for the data transfer to RAM12 and then informs the setting to ACU11. ACU11 receives the information of RAM12 based on the indication given from ROM1 in the synchronous mood and also delivers the data to control unit SIO corresponding to the designated circuit. SIO converts the received parallel data into the serial data and delivers it to the circuit. In this case, ACU11 checks whether the data of that time is the control code via ROM2 and memorizes the state. And in case the data is the control code, it is informed to CPU1 through RAM12. The above procedure can be given to each circuit, and thus a multiple control is possible for each circuit via ACU11 and firmware ROM1. So is at the reception time.
