Preliminary
5.6.6.2
The value in this register is used as the upper 14 bits of the interrupt vector VAB[20:0]. The lower 7 bits
are determined based on the highest priority interrupt and are then appended onto VBA before presenting
the full VAB to the Core.
Vector Address Bus (VAB) Bits 13—0

Fast Interrupt Match 0 Register (FIM0)
Figure 5-9 Fast Interrupt Match 0 Register (FIM0)
5.6.7.1
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
Reserved—Bits 15–6
5.6.7.2
These values determine which IRQ will be Fast Interrupt 0. 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.
Fast Interrupt 0 Vector Number (FAST INTERRUPT 0)—Bits 5–0

Fast Interrupt 0 Vector Address Low Register (FIVAL0)
Figure 5-10 Fast Interrupt 0 Vector Address Low Register (FIVAL0)
5.6.8.1
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.
