Question on the wait on peripheral pin instruction

Hello:
So when a waitpeq instruction is executed what frequency is the clock sampling the input pins?
That is it the PLL multiplied clock or some division of it?

cheers,
rich

    The pin is sampled at the PLL multiplied clock frequency.

    This is documented in the manual for the Spin waitpeq/waitpne commands (where such timing granuarity is irrelevant) but not in the PASM entry for waitpeq and waitpne (where it is highly relevant!)
