INPUTS, EXT MUX
The QADC allows external trigger inputs and the multiplexer outputs to be combined
onto some of the channel pins. All of the channel pins are used for at least two func-
tions, depending on the modes in use.
The following paragraphs describe QADC pin functions. Figure 8-2 shows the QADC
module pins.
PORT B ANALOG
PORT A ANALOG
The eight port A pins can be used as analog inputs, or as a bidirectional 8-bit digital
input/output port. Refer to the following paragraphs for more information.
