Programmable Registers
5.4.36 Interrupt Collector Interrupt Register 26
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_INTERRUPT26: 0x2C0
HW_ICOLL_INTERRUPT26_SET: 0x2C4
HW_ICOLL_INTERRUPT26_CLR: 0x2C8
HW_ICOLL_INTERRUPT26_TOG: 0x2CC
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.
EXAMPLE
HW_ICOLL_INTERRUPT26_SET(0,0x00000001);
