VCFG: Voltage Reference bit
1= VREF pin
0= VDD
bit 5-4
bit 3-2
Unimplemented: Read as zero
CHS1:CHS0: Analog Channel Select bits
00= Channel 00 (AN0)
01= Channel 0± (AN±)
10= Channel 02 (AN2)
11= Channel 03 (AN3)
bit ±
bit 0
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
ADON: A/D Conversion STATUS bit
1= A/D converter module is operating
0= A/D converter is shut-off and consumes no operating current
Legend:
R = Readable bit
W = Writable bit
’±’ = Bit is set
U = Unimplemented bit, read as ‘0’
’0’ = Bit is cleared x = Bit is unknown
- n = Value at POR
