GO/DONE: A/D Conversion Status bit
When ADON = 1
1 = A/D conversion in progress
0 = A/D conversion not in progress
Reserved: Always maintain this bit cleared.
ADON: A/D On bit
1 = A/D converter module is operating
0 = A/D converter module is shutoff and consumes no operating current

R = Readable bit
U = Unimplemented bit, read as ‘0’
ADCS1

Note:
(Setting this bit starts the A/D conversion. This bit is automatically cleared
by hardware when the A/D conversion is complete)
