EDIT: OOPS, you are correct, you would need IOC for portA ... Sorry...
__________________________________________________ _______________
RAC_INT is for portA.

(from http://darreltaylor.com/DT_INTS-14/intro.html )
RAC_INT -- RA Port Change (for port A)
RBC_INT -- RB Port Change Interrupt (for port B)
RABC_INT -- RAB Port Change (for port A or B)

Here is a small example for RAC_INT , but it's just for a push button.

thats OK Walter, you had me thinking for the last hour or 2! (Now have to reset all the smoke alarms)

But back to it, any thoughts on my timing? Anyone? My brain is still locked about this. I want to draw me some timing diagrams, but it seems I have become so dependent on puters, I don't have any suitable graph paper to do so with. I am somewhat of a stickler when it comes to these things.

Inspired by Daves wonderful gift, I worked out some timing in my schmatic program (with snaps). It looks to me with 5uS interupts, I will not miss a single step. I will strech them sometimes and shrink them sometimes, but thats no problem. And I still have 40 instructions between interupts. Well prolly more like 30 when you account for the interupt handler itself.

So I think I am off to the races now!!
