Preliminary
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.
5.6.13 Fast Interrupt 0 Vector Address Low Register (FIVAL0)
Figure 5-15 Fast Interrupt 0 Vector Address Low Register (FIVAL0)
5.6.13.1 Fast Interrupt 0 Vector Address Low (FIVAL0)—Bits 15–0
The lower 16 bits of the vector address are 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.
5.6.14 Fast Interrupt 0 Vector Address High Register (FIVAH0)
Figure 5-16 Fast Interrupt 0 Vector Address High Register (FIVAH0)
5.6.14.1 Reserved—Bits 15–5
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.14.2 Fast Interrupt 0 Vector Address High (FIVAH0)—Bits 4–0
The upper five bits of the vector address are 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.
5.6.15 Fast Interrupt 1 Match Register (FIM1)
Figure 5-17 Fast Interrupt 1 Match Register (FIM1)
5.6.15.1 Reserved—Bits 15–7
This bit field is reserved or not implemented. It is read as 0, but cannot be modified by writing.
