5.6.23.2
This register combines with the other five to represent the pending IRQs for interrupt vector numbers 2
through 85.

5.6.30
5.6.30.1
This read-only bit reflects the state of the interrupt to the 56800E core.
5.6.30.2
These read-only bits reflect the state of the new interrupt priority level bits being presented to the 56800E
core at the time the last IRQ was taken. This field is only updated when the 56800E core jumps to a new
interrupt service routine.
