Problem with LPC932A1

Vic de la Rosa

Hi,

I can't seem to get the external interrupts to work on the 89LPC932A1. Example: when I set EX1 to low level trigger (IT1=0), the interrupt routine gets called no matter what the level of P1.4 is. and when IT1=1, the interrupt routine gets called once. so it appears that INT1 input is always low.

TIA
Vic
