Interrupt level for queue 1. A value of 0b00000 provides an interrupt level of 0; 0b11111 provides
a level interrupt. All interrupts are presented on the IMB3. Interrupt level priority software deter-
mines which level has the highest priority request.

Port A pins are referred to as PQA when used as an 8-bit input/output port. Port A can also be
used for analog inputs (AN[59:52]), and external multiplexer address outputs (MA[2:0]).
Port B pins are referred to as PQB when used as an 8-bit input-only port. Port B can also be used
for non-multiplexed (AN[51:48])/AN[3:0]) and multiplexed (ANz, ANy, ANx, ANw) analog inputs.
