18.6.1 Port QA Pin Functions
The four port QA pins can be used as analog inputs or as a bidirectional
4-bit digital input/output port.
18.6.1.1 Port QA Analog Input Pins
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.
