Preliminary
routine based on values in the Fast Interrupt Vector Address registers without having to go to a jump table
first; see Part 5.3.3. IRQs used as fast interrupts must be set to priority level 2. Unexpected results will
occur if a fast interrupt vector is set to any other priority. Fast interrupts automatically become the
highest-priority level 2 interrupt, regardless of their 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 Table 4-5.

Fast Interrupt 1 Vector Address Low Register (FIVAL1)
Figure 5-18 Fast Interrupt 1 Vector Address Low Register (FIVAL1)
5.6.16.1
Fast Interrupt 1 Vector Address Low (FIVAL1)—Bits 15–0
The lower 16 bits of vector address are 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.
5.6.17
Fast Interrupt 1 Vector Address High Register (FIVAH1)

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.
