bit 7-6:

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

If internal VRL and/or VRH are not used for A/D reference (VCFG<2:0> = 000, 001, 011 or 101):

00 = FOSC/2

01 = FOSC/8

10 = FOSC/32

11 = FRC (clock derived from a dedicated RC oscillator = 1 MHz max)

If internal VRL and/or VRH are used for A/D reference (VCFG<2:0> = 010, 100, 110 or 111):

00 = FOSC/16

01 = FOSC/64

10 = FOSC/256

11 = FRC (clock derived from a dedicated RC oscillator = 125 kHz max)

bit 1,5-3: CHS:<3:0>: Analog Channel Select bits

0000 = channel 00 (AN0)

0001 = channel 01 (AN1)

0010 = channel 02 (AN2)

0011 = channel 03 (AN3)

0100 = channel 04 (AN4)

0101 = channel 05 (AN5)

0110 = reserved, do not select

0111 = reserved, do not select

1000 = reserved, do not select

1001 = reserved, do not select

1010 = reserved, do not select

1011 = reserved, do not select

1100 = reserved, do not select

1101 = reserved, do not select

1110 = reserved, do not select

1111 = reserved, do not select

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 0:

ADON: A/D On bit

1 = A/D converter module is operating

0 = A/D converter is shutoff and consumes no operating current
