Interrupt vector is set to any other priority. A Fast Interrupt automatically becomes the highest-priority
level 2 interrupt regardless of its location in the interrupt table prior to being declared as Fast Interrupt.
Fast Interrupt 0 has priority over Fast Interrupt 1. To determine the vector number of each IRQ, refer to
the vector table.
5.5.11
Fast Interrupt 1 Vector Address Low Register (FIVAL1)
Figure 5-13 Fast Interrupt 1 Vector Address Low Register (FIVAL1)
5.5.11.1
Fast Interrupt 1 Vector Address Low (FIVAL1)—Bits 15–0
The lower 16 bits of the vector address used for Fast Interrupt 1. This register is combined with FIVAH1
to form the 21-bit vector address for Fast Interrupt 1 defined in the FIM1 register.
5.5.12
Fast Interrupt 1 Vector Address High Register (FIVAH1)
Figure 5-14 Fast Interrupt 1 Vector Address High Register (FIVAH1)
5.5.12.1
Reserved—Bits 15–5
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.5.12.2
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.
5.5.13
IRQ Pending Register 0 (IRQP0)
Figure 5-15 IRQ Pending Register 0 (IRQP0)
5.5.13.1
IRQ Pending (PENDING)—Bits 15–1
This register combines with IRQP1 and IRQP2 to represent the pending IRQs for interrupt vector numbers
2 through 45.
