A/D Conversions

Clearing the GO/DONE bit during a conversion will abort the current conversion. The A/D result
register pair will NOT be updated with the partially completed A/D conversion sample. That is,
the ADRESH:ADRESL registers will continue to contain the value of the last completed conver-
sion (or the last value written to the ADRESH:ADRESL registers). After the A/D conversion is
aborted, a 2T
sition on the selected channel is automatically started.

The GO/DONE bit should NOT be set in the same instruction that turns on the A/D,
due to the required acquisition time requirement.
