Just a quickie, re IOC interrupts....how do I know which one to use? (previously I was using IOC with a 16f690 & used RABC_INT then, but the PIC I'm using now doesn't have a PORT B)

From DT's site...

Several new interrupt sources have been added in version 1.00. GPC_INT, IOC_INT, RAC_INT, RABC_INT and the original RBC_INT are all forms of Port Change Interrupts. The chip being programmed determines which one you need to use.

Where do I look to establish this info?

I'm using one of the newer 14 pin 16F1823 PICs.
