I had a memory of problems with certain chips with the high ports at
about the time of this compiler. I think the compiler does attempt to
set ANSG, but actually accesses the wrong register. However the
register location is correct in the database used by the SFR access.
It was a niggling memory of mine, which is why I suggested it....

The crazy thing is that if I don't declare

Code:
setup_adc_ports(sAN12|sAN15|VSS_VDD);


The ANSG is setup properly and UART2 works ok. Confused Rolling Eyes
So I'm explicitly declaring that ONLY AN12 & AN15 must be analog.

Anyway, lesson learned. Wink

I didn't see the second page.
If you are correct, I see some hard developing times for me. Confused Rolling Eyes
