#175268 - so only one Ext.int pin will do Responding to: ???'s previous message |
Thanks stefan,
As mentioned in my earlier post, i have already used INT0 pin for another job i,e decoding IR signals and i have INT1 connected to ZCD signal, that implies that P3.3 (INT1) is the gate for TR1 and ZCD pulses should be given to INT1 alone and not T1 pin Regards, Arun |
