bit 7 bit 0

Legend:

R = Readable bit W = Writable bit

u = Bit is unchanged x = Bit is unknown U = Unimplemented bit, read as ‘0’

‘1’ = Bit is set ‘0’ = Bit is cleared -n/n = Value at POR and BOR/Value at all other Resets

bit 7 Unimplemented: Read as ‘0’

bit 6-2 CHS<4:0>: Analog Channel Select bits

00000 =AN0

00001 =AN1

00010 =AN2

00011 =AN3

00100 = Reserved; no channel connected

•

11100 = Reserved; no channel connected

11101 = Temperature indicator

(1)

11110 = DAC (Digital-to-Analog Converter)

(2)

11111 = FVR (Fixed Voltage Reference) Buffer 1 output

(3)

bit 1 GO/DONE: ADC Conversion Status bit

1 = ADC conversion cycle is 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
