Hello!!
i have a question. i have some code and hardware implmented.
it would help me now, if i could use an interruption for the pinD4.
is it possible to use the PSP interrupt function for this pin only??
thanks! |

First, any question of this sort, _must_ tell us what processor is involved. There are hundreds of variants of PICs, and hardware questions asked without this data, are unlikely to get an accurate answer.
However that being said, the answer is almost certainly 'no'. The PSP, does not possess an ability to interrupt from a data pin (interrupts on the PSP, are triggered from the read/write control lines, not the data lines). Also PSP mode, affects the whole port.
