Unimplemented: Read as '0'
GO/DONE: A/D Conversion Status bit
If ADON = 1
1 = A/D conversion in progress (setting this bit starts the A/D conversion which is automatically cleared
by hardware when the A/D conversion is complete)
0 = A/D conversion not in progress
bit 1:
bit 0:
Unimplemented: Read as '0'
ADON: A/D On bit
1 = A/D converter module is operating
0 = A/D converter module is shutoff and consumes no operating current
