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 QA and QB 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. 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 a 4-bit, digital
input-only port. 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.
