GO/DONE: A/D Conversion Status bit
When ADON = 1
1 = A/D conversion in progress (setting this bit starts the A/D conversion which is
0 = A/D conversion not in progress
Unimplemented: Read as '0'
ADON: A/D On bit
1 = A/D converter module is powered up
0 = A/D converter module is shut off and consumes no operating current
