CPUIRQ: Interrupt Request from Interrupt Controller CPU bit
1 = An interrupt request has occurred but has not yet been Acknowledged by the CPU (this will
0 = No interrupt request is left unacknowledged
Unimplemented: Read as ‘0’
VHOLD: Allows Vector Number Capture and Changes what Interrupt is Stored in VECNUM bit
1 = VECNUM will contain the value of the highest priority pending interrupt, instead of the current
0 = VECNUM will contain the value of the last Acknowledged interrupt (last interrupt that has occurred
Unimplemented: Read as ‘0’
