AD conversion on all PIC's is done in hardware completely independently. You can have interrupts shooting off all over the place without worry.

At the end of the AD conversion, you can either check the DONE flag to see your result is ready to be picked up, or have the AD generate an interrupt for you to tell you it's done, or have it all done for you by ADCIN.

Personally, I find ADCIN a handicap especially if you have interrupts you don't want to miss. It's easier to access the registers and do all the ADC work directly. If you can't figure it for yourself, come back to me and I'll show you how.
