CHS3

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

Unimplemented: Read as ‘0’

bit 5-2

CHS<3:0>: Analog Channel Select bits

0000 =AN0

0001 =AN1

0010 =AN2

0011 =AN3

0100 =AN4

0101 =AN5

0110 =AN6

0111 =AN7

1000 =AN8

1001 =AN9

1010 =AN10

1011 =Reserved

1100 =Reserved

1101 =Reserved

1110 =Reserved

1111 = Fixed Voltage Reference (FVREF)

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
