bit 2
GO/DONE: A/D Conversion Status bit
If ADON = 1:
1 = A/D conversion in progress (setting this bit starts the A/D conversion)
0 = A/D conversion not in progress (this bit is automatically cleared by hardware when the A/D
conversion is complete)
bit 1
Unimplemented: Read as ‘0’
bit 0
ADON: A/D On bit
1 = A/D converter module is operating
0 = A/D converter module is shut off and consumes no operating current
