7.2.7 ADC REGISTER DEFINITIONS

The following registers are used to control the

operation of the ADC.

R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 U-0 R/W-0

ADCS1 ADCS0 CHS2 CHS1 CHS0 GO/DONE

—

ADON

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 ADCS<1:0>: A/D Conversion Clock Select bits

00 = F

OSC/2

01 = F

OSC/8

10 = F

OSC/32

11 = F

RC (Clock derived from the internal ADC RC oscillator)

bit 5-3 CHS<2:0>: Analog Channel Select bits

000 = AN0

001 = AN1

010 = AN2

011 = AN3

100 = Reserved, do not use

101 = Reserved, do not use

110 = Reserved, do not use

111 = Reserved, do not use

bit 2 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 1 Unimplemented: Read as ‘0’

bit 0 ADON: ADC Enable bit

1 = ADC is enabled

0 = ADC is disabled and consumes no operating current
