INT0
O4 Interrupt generated by HDLC, RxC/I or RxMON. Active high.
50
INT1
O4 Interrupt1.This pin goes to 5V when the selected clock A (or B) has disappeared ;
250µs after reset this pin goes to 5V also if clock A is not present.
4
WDO
O4 Watch Dog Output.This pin goes to 5V during 1ms when the microprocessor has not
reset the Watch Dog during the programmable time.
Type : I1 = Input TTL ;
I2 = I1 + Pull-up ;
O4 = Output CMOS 4mA ;
O4T = O4 + Tristate ;
O8D = Output CMOS 8mA, Open Drain ;
O8T = Output CMOS 8mA, Tristate
I3 = I1 + Hysteresis ;
I4 = I3 + Pull-up ;
O8 = Output CMOS 8mA, ”1” and ”0” at Low Impedance ;
O8DT = Output CMOS 8mA, Open Drain or Tristate ;
