5.5.8

Fast Interrupt 0 Vector Address Low Register (FIVAL0)

Figure 5-10 Fast Interrupt 0 Vector Address Low Register (FIVAL0)

5.5.8.1

Fast Interrupt 0 Vector Address Low (FIVAL0)—Bits 15—0

The lower 16 bits of the vector address used for Fast Interrupt 0. This register is combined with FIVAH0

to form the 21-bit vector address for Fast Interrupt 0 defined in the FIM0 register.

5.5.9

Fast Interrupt 0 Vector Address High Register (FIVAH0)

Figure 5-11 Fast Interrupt 0 Vector Address High Register (FIVAH0)

5.5.9.1

Reserved—Bits 15–5

This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.

5.5.9.2

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.

5.5.10

Fast Interrupt 1 Match Register (FIM1)

5.5.10.1

Reserved—Bits 15–6

This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.

5.5.10.2

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
