Legend:
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 7
Unimplemented: Read as ‘0’

bit 1
GO/DONE: ADC Conversion Status bit
1 = ADC conversion cycle in progress. Setting this bit starts an ADC conversion cycle.
This bit is automatically cleared by hardware when the ADC conversion has completed.
0 = ADC conversion completed/not in progress
bit 0
ADON: ADC Enable bit
1 = ADC is enabled
0 = ADC is disabled and consumes no operating current
Note 1: See Section 14.0 “Fixed Voltage Reference (FVR)” for more information.
2: See Section 15.0 “Temperature Indicator Module” for more information.
3: AN<7:5> and AN<27:20> are PIC16(L)F1517/9 only.
