also have some general-purpose input or input/output functionality. In
addition, there are also two analog reference pins and two analog
submodule power pins.
The QADC has external trigger inputs and multiplexer outputs that are
shared with some of the analog input pins.
The four port QA pins can be used as analog inputs or as a bidirectional
4-bit digital input/output port.
When used as analog inputs, the four port QA pins are referred to as
AN[56:55, 53:52]. Due to the digital output drivers associated with
port QA, the analog characteristics of port QA may be different from
those of port QB.
