I now have an urgent (been waiting for the 40X2) application that needs six ADC channels and would like to know if it is possible to enable any of the 28X1 additional analog inputs (AN8-AN13) shown on the PIC16F886 data sheet? It seems quite easy to enable additional analog channels on the 14M and -not so easily- on the 18X. I have not been able to find any documentation about doing this on the 28 or 40X1 and would very much appreciate any relevant information.
