Legend:
R = Readable bit
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
u = Bit is unchanged
x = Bit is unknown
-n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set
‘0’ = Bit is cleared

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
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
