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

R/W-0

—

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

1010

= AN10

1011

= AN11

1100

= AN12

1101

= AN13

1110

= Reserved

1111

= Fixed Voltage Reference (FV

REF

)

bit 1

GO/DONE: A/D Conversion Status bit

= 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

= ADC is disabled and consumes no operating current
