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
