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.

Fast Interrupt 1 Vector Address Low Register (FIVAL1)
Figure 5-15 Fast Interrupt 1 Vector Address Low Register (FIVAL1)
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.
5.6.14
Fast Interrupt 1 Vector Address High (FIVAH1)
Figure 5-16 Fast Interrupt 1 Vector Address High Register (FIVAH1)
5.6.14.1
Reserved—Bits 15–5
This bit field is reserved. Each bit must be set to 0.
5.6.14.2
Fast Interrupt 1 Vector Address High (FIVAH1)—Bits 4–0
The upper five bits of the vector address 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.
