Programmable Registers
5.4.3 Interrupt Collector Control Register (HW_ICOLL_CTRL)
The Interrupt Collector Control Register provides overall control of interrupts being routed
to the CPU. This register is not at offset zero from the block base because that location is
needed for single 32 bit instructions to be placed in the exception vector location.
HW_ICOLL_CTRL: 0x020
HW_ICOLL_CTRL_SET: 0x024
HW_ICOLL_CTRL_CLR: 0x028
HW_ICOLL_CTRL_TOG: 0x02C
This register handles the overall control of the interrupt collector, including soft reset and
clock gate. In addition, it handles state machine variations like NO_NESTING and ARM
read side effect processing on the vector address register.
