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
when the CPU priority is higher than the interrupt priority
0 = No interrupt request is unacknowledged
Reserved: Maintain as ‘0’
VHOLD: Vector Number Capture Configuration bit
1 = VECNUM<6:0> contain the value of the highest priority pending interrupt
0 = VECNUM<6:0> contain the value of the last Acknowledged interrupt (i.e., the last interrupt that has
occurred with higher priority than the CPU, even if other interrupts are pending)
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<6:0>: Vector Number of Pending Interrupt or Last Acknowledged Interrupt bits
When VHOLD = 1:
Indicates the vector number (from 0 to 118) of the last interrupt to occur.
When VHOLD = 0:
Indicates the vector number (from 0 to 118) of the interrupt request currently being handled.
