5.4.138 Interrupt Collector Debug Register 0 (HW_ICOLL_DEBUG)
The contents of this register will be defined as the hardware is developed.
HW_ICOLL_DEBUG: 0x1120
HW_ICOLL_DEBUG_SET: 0x1124
HW_ICOLL_DEBUG_CLR: 0x1128
HW_ICOLL_DEBUG_TOG: 0x112C
This register provides diagnostic visibility into the IRQ request state machine and its various
inputs.
EXAMPLE
if (BF_RD(ICOLL_DEBUG, LEVEL_REQUESTS) != HW_ICOLL_DEBUG_LEVEL_REQUESTS__LEVEL3)
TPRINTF(TP_MED, ("ICOLL INSERVICE = 0x%x\n", BF_RD(ICOLL_DEBUG, INSERVICE)));
TPRINTF(TP_MED, ("ICOLL STATE = 0x%x\n", BF_RD(ICOLL_DEBUG, VECTOR_FSM)));
