PURPOSE:To enable to receive an input data normally, by loading the input data in the first-in first-out queue, in case the input data of the circuit control memory is not received by the communication control processor due to a temporary increase of load. CONSTITUTION:When the communication control processor CCP has received a data of the circuit control memory LCW, the queue control part QCTL outputs a data on a first-come-first-served basis from the first-in first-out queue LQ in accordance with the command from the processor CCP. The circuit number QLi which has been indicated, and the circuit number Li which has been output from the queue LQ are compared by the comparator circuit MAT. In case of coincidence, the output DTi from the queue LQ at that time is input to the memory LCW. Other data are input again to the queue LQ on a first-come-first-served basis. |
