Circuit Reset
Chip Select 0 : internal registers are selected
Chip Select 1 : external memory is selected
Interrupt generated by HDLC, RxC/I or RxMON. Active high.
Interrupt1.This pin goes to 5V when the selected clock A (or B) has disappeared ;
250 s after reset this pin goes to 5V also if clock A is not present.
Watch Dog Output.This pin goes to 5V during 1ms when the microprocessor has not
reset the Watch Dog during the programmable time.
