A/D Registers
These channels are not implemented on 28-pin devices.
Performing a conversion on unimplemented channels will return random values.
Channel 28 turns off analog MUX switches to allow for minimum capacitive loading of the ADC input, for
finer resolution CTMU time measurements.
A/D CONTROL REGISTERS
Unimplemented: Read as ‘ 0 ’
CHS<4:0>: Analog Channel Select bits
00000 = Channel 00 (AN0)
00001 = Channel 01 (AN1)

00111 = Channel 07 (AN7)
01000 = Channel 08 (AN8)

GO/DONE: A/D Conversion Status bit
1 = A/D cycle is in progress. Setting this bit starts an A/D conversion cycle. The bit is cleared
0 = A/D conversion has completed or is not in progress
ADON: A/D On bit
1 = A/D Converter is operating
0 = A/D conversion module is shut off and consuming no operating current
