Programmable Registers
5.4.33 Interrupt Collector Interrupt Register 23
This register provides a mechanism to specify the priority level for an interrupt source. It
also provides an enable and software interrupt for each one, as well as security designation.
HW_ICOLL_INTERRUPT23: 0x290
HW_ICOLL_INTERRUPT23_SET: 0x294
HW_ICOLL_INTERRUPT23_CLR: 0x298
HW_ICOLL_INTERRUPT23_TOG: 0x29C
This register provides a mechanism to specify the priority associated with an interrupt bit.
In addition, this register controls the enable and software generated interrupt. WARNING:
Modifying the priority of an enabled interrupt may result in undefined behavior. You should
always disable an interrupt prior to changing its priority.
