Programmable Registers
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.

Always write zeroes to this bitfield.
Set this to 1 to steer this interrupt to the non-vectored FIQ line. When set to 0 the interrupt will pass through
the main IRQ FSM and priority logic.
0x0
0x1
Set this bit to one to force a software interrupt.
0x0
0x1
Enable the interrupt bit through the collector.
0x0
0x1
Set the priority level for this interrupt, 0x3 is highest, 0x0 is lowest (weakest).
