1 SET Interrupt Set: W 0
CPU write of 1 to the SETn bit causes the tpcc_intN output signal to
be pulsed egardless of state of interrupts enable (IERn) and status
(IPRn).
CPU write of 0 has no effect.
0 EVAL Interrupt Evaluate: W 0
CPU write of 1 to the EVALn bit causes the tpcc_intN output signal
to be pulsed if any enabled interrupts (IERn) are still pending
(IPRn).
CPU write of 0 has no effect.

Address Offset 0x1080
Physical address 0x01C0 1080 Instance IVA2.2 TPCC
Description QDMA Event Register:
If QER.En bit is set, then the corresponding QDMA channel is prioritized vs. other qdma events for submission to
the TC. QER.En bit is set when a vbus write byte matches the address defined in the QCHMAPn register. QER.En
bit is cleared when the corresponding event is prioritized and serviced. QER.En is also cleared when user writes a
1 to the QSECR.En
bit. If the QER.En bit is already set and a new QDMA event is detected due to user write to QDMA trigger location
and QEER register is set, then the corresponding bit in the QDMA Event Missed Register is set.
