Hello Ghoot,

Ghoot>>Hi Dwayne,It says "2 Analog (comparators)", but doesn't say "ADC" like I've seen on some chips...is that the problem?
Thanks for your reply,<<

ADCON is the A/D converters on the chip...Unfortuantely do you do not have *any* AD's on the 648. the 648 does have 2 comparators...

CMCOM=7 will make 648A Digital instead of analog. Turning on those little Comparitors. <g>

Sorry I can't be of more help right now.

Dwayne
