5.4.9 Interrupt Collector Raw Interrupt Input Register 3
Interrupt hardware-source states 96-127 are visible in this read-only register.
HW_ICOLL_RAW3: 0x0D0
HW_ICOLL_RAW3_SET: 0x0D4
HW_ICOLL_RAW3_CLR: 0x0D8
HW_ICOLL_RAW3_TOG: 0x0DC
This register provides a read-only view of the raw interrupt request lines coming from
various parts of the chip. The purpose is to improve diagnostic observability. Note that these
only capture the state of hardware interrupt sources.
