5.5.16.1
This read-only bit reflects the state of the interrupt to the 56800E core.
5.5.16.2
These read-only bits reflect the state of the new interrupt priority level bits being presented to the 56800E
core. These bits indicate the priority level needed for a new IRQ to interrupt the current interrupt being
sent to the 56800E core. This field is only updated when the 56800E core jumps to a new interrupt service
routine.
Note:
5.5.16.3
This read-only field shows the vector number (VAB[6:0]) used at the time the last IRQ was taken. In the
case of a Fast Interrupt, it shows the lower address bits of the jump address. This field is only updated when
the 56800E core jumps to a new interrupt service routine.
Note:
5.5.16.4
This bit allows all interrupts to be disabled.

0 = No interrupt is being sent to the 56800E core
1 = An interrupt is being sent to the 56800E core
00 = Required nested exception priority levels are 0, 1, 2, or 3
01 = Required nested exception priority levels are 1, 2, or 3
10 = Required nested exception priority levels are 2 or 3
11 = Required nested exception priority level is 3
0 = Normal operation (default)
1 = All interrupts disabled
Nested interrupts may cause this field to be updated before the original interrupt service routine can
read it.
