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.
Note:
5.6.30.3
This read-only field shows the vector number (VAB[7:1]) used at the time the last IRQ was taken. This
field is only updated when the 56800E core jumps to a new interrupt service routine.
