To keep it short, I'm replacing a legacy PIC with a modern one (16C711 to 16F819) in a old project. I need a Digital Out on pin RA3 (no input, A or D), but the A/D config table will not allow the mix of A/D to digital I/O I used on the previous 16c711.

Sooo, if I have the ADCON1 setting to have an A/D on RA3 (and RA0 & RA1 in my case) but have TrisA set to Digital Out on RA3 will I cause any problems for the PIC while driving the pin as digital out?

I've used PIC A/D's heaps in the past but alway kept the digital functions well apart from the analogue.

Cheers,
Martin
