ADCS1:ADCS0: A/D Conversion Clock Select bits
If ADCS2 = 0:
000 = FOSC/2
001 = FOSC/8
010 = FOSC/32
011 = FRC (clock derived from an RC oscillation)
If ADCS2 = 1:
00 = FOSC/4
01 = FOSC/16
10 = FOSC/64
11 = FRC (clock derived from an RC oscillation)
CHS<2:0>: 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)⁽¹⁾
0110 = Channel 06 (AN6)⁽¹⁾
0111 = Channel 07 (AN7)⁽¹⁾
1000 = Channel 08 (AN8)
1001 = Channel 09 (AN9)
1010 = Channel 10 (AN10)
1011 = Channel 11 (AN11)
1100 = Channel 12 (AN12)
1101 = Channel 13 (AN13)
111x = Unused
Note 1: Selecting AN5 through AN7 on the 28-pin product variant (PIC16F737 and
PIC16F767) will result in a full-scale conversion as unimplemented channels are
connected to VDD.
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
CHS<3>: Analog Channel Select bit (see bit 5-3 for bit settings)
ADON: A/D Conversion Status bit
1 = A/D converter module is operating
0 = A/D converter is shut-off and consumes no operating current
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
