Pin No. Signal I/O Description
17 INT1 IN Signal to synchronize LSI with commercial power source frequency.
This is basic timing for all real time process-
ing of LSI.
18-19 AIN0-AIN1 IN Terminal to change functions according to the model.
Signal in accordance with the model in operation is applied to set up its function.
20 AIN2 IN Input signal which communicates the door open/close information to LSI.
Door closed; "H" level signal.
Door opened; "L" level signal.
21 AIN3 IN Terminal to change functions according to the model.
Signal in accordance with the model in operation is applied to set up its function.
