bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
u = Bit is unchanged
x = Bit is unknown
-n = Value at POR
‘1’
= Bit is set
‘0’
= Bit is cleared
bit 7
Unimplemented: Read as ‘0’

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
