9.2.7 ADC REGISTER DEFINITIONS
The following registers are used to control the
operation of the ADC.
REGISTER 9-1: ADCON0: A/D CONTROL REGISTER 0
U-0 U-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0

bit 7 bit 0
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 7-6 Unimplemented: Read as ‘0’
bit 5-2 CHS<3:0>: Analog Channel Select bits

1100 =AN12
1101 =AN13
1110 =Reserved
1111 = Fixed Voltage Reference (FV
REF)
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
