Hi is there anyway of knowing if the LPC is receiving pulses on its INT0 pin. I have it already set up like this:
IT0 = 1; //Pulses are edge detected
EX0 = 1; //interrupt enable bit
EA =1;

It works fine, but is there anyway to find out if the pulses have stopped coming into this pin? The time the pulses will be present at this pin is unknown.
