5.6.11.2
Fast Interrupt 0 Vector Address High (FIVAH0)—Bits 4–0
The upper five bits of the vector address used for Fast Interrupt 0. This register is combined with FIVAL0
to form the 21-bit vector address for Fast Interrupt 0 defined in the FIM0 register.

Fast Interrupt 1 Match Register (FIM1)

5.6.12.1
Reserved—Bits 15–6
This bit field is reserved. Each bit must be set to 0.
5.6.12.2
Fast Interrupt 1 Vector Number (FAST INTERRUPT 1)—Bits 5–0
These values determine which IRQ will be Fast Interrupt 1. Fast Interrupts vector directly to a service
routine based on values in the Fast Interrupt Vector Address registers without having to go to a jump table
first. 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. 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.

5.6.13.1
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.
