CH[2:0] — Channel Select Bits
These read/write bits select one of eight ADC input channels as
shown in
Table 26
. Channels 0–3 are the input pins, PC3/AN3,
PC4/AN2, PC5/AN1, and PC6/AN0. Channels 4–6 can be used for
reference measurements. Channel 7 is reserved for factory testing.
To prevent excess power dissipation, do not use an ADC pin as an
analog input and a digital input at the same time.
Using one of the port pins as the ADC input does not affect the ability to
use the remaining port pins as digital inputs.
Reading a port pin that is selected as an analog input returns a logic 0.
