Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown

bit 1
GO/DONE: A/D Conversion Status bit
1
= A/D conversion cycle in progress. Setting this bit starts an A/D conversion cycle.
This bit is automatically cleared by hardware when the A/D conversion has completed.
0
= A/D conversion completed/not in progress
bit 0
ADON: ADC Enable bit
1
= ADC is enabled
0
= ADC is disabled and consumes no operating current
