#82995 - please carify
Responding to: ???'s previous message
Having EX1 = 1; and its pin high
I assume you mean the interrupt pin.

Do you have an ISR for EI1?

I can see no way you "predict" when Int1 goes low and disabling the interrupt only prior to and during that time does not make any sense.

If an interrupt is disabled (EX1 = 0) will not hinder the detection of the interrupt, when you anable it the detected interrupt will vector to the ISR.
