The 16F872 doc references "PicMicro Mid-Range MCU Family Reference Manual (DS33023)" for more info on how to use the A/D converters. Tried microchip's website but get an "overflow" on search. Google comes up with nothing. Anyone know where I can get this doc or other tutorial on the A/D converter? The datasheet itself is not too = specific/descriptive.
