5.6.12
5.6.12.1
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.12.2
This value determines which IRQ will be a 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; see
results will 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
5.6.13
5.6.13.1
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.
5.6.14
5.6.14.1
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
