REGISTER 23-6:

AD1CHS0: ADC1 INPUT CHANNEL 0 SELECT REGISTER (CONTINUED)

Note 1:

AN0 through AN7 are repurposed when comparator and op amp functionality is enabled. See

Figure 23-1

to determine how enabling a particular op amp or comparator affects selection choices for Channels 1, 2
and 3.

The OAx input is used if the corresponding op amp is selected (OPMODE (CMxCON<10>) = 1);
otherwise, the ANx input is used.

See the

“Pin Diagrams”

section for the available analog channels for each device.
