Table 111. Vector Address registers 0-31 (VICVectAddr0-31 - addresses 0xFFFF F100 to
27C)
These registers select a priority level for the 32 vectored IRQs. There are 16 priority
levels, corresponding to the values 0 through 15 decimal, of which 15 is the lowest priority.
The reset value of these registers defaults all interrupt to the lowest priority, allowing a
single write to elevate the priority of an individual interrupt.
Table 112. Vector Priority registers 0-31 (VICVectPriority0-31 - addresses 0xFFFF F200 to
When an IRQ interrupt occurs, the address of the Interrupt Service Routine (ISR) for the
interrupt that is to be serviced can be read from this register. The address supplied is from
one of the Vector Address Registers (VICVectAddr0-31).

The Software Priority Mask Register contains individual mask bits for the 16 interrupt
priority levels.
