Hi Josh,

The INT_INT should work ok, even with it on PORTA.

For the Interrupt on change with PORTA and PORTB, just add these two lines in the ASM section right before the INT_LIST

RBIF = RABIF
RBIE = RABIE
(no space at the beginning of the line)

Then use RBC_INT. I'll add RABC_INT, C1_INT and C2_INT names in DT_INTS-14 later, but that should get you going for now.

HTH,
