CPUIRQ: Interrupt Request from Interrupt Controller CPU bit
1 = An interrupt request has occurred but has not yet been Acknowledged by the CPU; this happens
0 = No interrupt request is unacknowledged
Unimplemented: Read as ‘0’
VHOLD: Vector Number Capture Configuration bit
1 = The VECNUM bits contain the value of the highest priority pending interrupt
0 = The VECNUM bits contain the value of the last Acknowledged interrupt (i.e., the last interrupt that
Unimplemented: Read as ‘0’
ILR<3:0>: New CPU Interrupt Priority Level bits
1111 = CPU Interrupt Priority Level is 15

0001 = CPU Interrupt Priority Level is 1
0000 = CPU Interrupt Priority Level is 0
Unimplemented: Read as ‘0’
VECNUM<5:0>: Vector Number of Pending Interrupt or Last Acknowledged Interrupt bits
VHOLD = 1: The VECNUM bits indicate the vector number (from 0 to 118) of the last interrupt to occur
VHOLD = 0: The VECNUM bits indicate the vector number (from 0 to 118) of the interrupt request
