Preliminary
5.6.17.1
Reserved—Bits 15–5
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.17.2
Fast Interrupt 1 Vector Address High (FIVAH1)—Bits 4–0
The upper five bits of the vector address are used for Fast Interrupt 1. This register is combined with
FIVAL1 to form the 21-bit vector address for Fast Interrupt 1 defined in the FIM1 register.
5.6.18
IRQ Pending 0 Register (IRQP0)
Figure 5-20 IRQ Pending 0 Register (IRQP0)
5.6.18.1
IRQ Pending (PENDING)—Bits 16–2
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
5.6.18.2
Reserved—Bit 0
This bit is reserved or not implemented. It is read as 1 and cannot be modified by writing.
5.6.19
IRQ Pending 1 Register (IRQP1)
Figure 5-21 IRQ Pending 1 Register (IRQP1)
5.6.19.1
IRQ Pending (PENDING)—Bits 32–17
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
