SECTION 2 SIGNAL DESCRIPTIONS
The QADC uses a maximum of 21 external pins. There are 16 channel/port pins that
can support up to 44 channels when external multiplexing is used (including internal
channels). All of the channel pins can also be used as general-purpose digital port
pins. In addition, there are also two analog reference pins, two analog submodule pow-
er pins, and one V
SSE
pin for the open drain output drivers on port A.
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.
QADC module pins.
