QADCTEST is used only during factory testing of the MCU. Attempts to
access this register outside of factory test mode will result in access
privilege violation.
QADC ports A and B are accessed through two 8-bit port data registers
(PORTQA and PORTQB).
Port QA pins are referred to as PQA[4:3, 1:0] when used as a
bidirectional, 4-bit, input/output port that may be used for
general-purpose digital input signals or digital output signals. Port QA
can also be used for analog inputs (AN[56:55, 53:52]), external trigger
inputs (ETRIG[2:1]), and external multiplexer address outputs (MA[1:0]).
Port QB pins are referred to as PQB[3:0] when used as an input-only,
4-bit, digital port that may be used for general-purpose digital input
signals. Data for PQB[3:0] is accessed from PORTQB. Port QB can also
be used for non-multiplexed (AN[3:0]) and multiplexed (ANz, ANy, ANx,
ANw) analog inputs.
PORTQA and PORTQB are not initialized by reset.
