56F8356 Technical Data
Preliminary
5.6.23.2 IRQ Pending (PENDING)—Bit 81
This register combines with the other five to represent the pending IRQs for interrupt vector
numbers 2 through 81.
0 = IRQ pending for this vector number
1 = No IRQ pending for this vector number

5.6.30.1 Interrupt (INT)—Bit 15
This
read-only
bit reflects the state of the interrupt to the 56800E core.
0 = No interrupt is being sent to the 56800E core
1 = An interrupt is being sent to the 56800E core
5.6.30.2 Interrupt Priority Level (IPIC)—Bits 14–13
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:
Nested interrupts may cause this field to be updated before the original interrupt service
routine can read it.
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
