NOTES:
1. Allocate interrupt vectors in even addresses.
2. Vectors are fixed to even addresses.
11.6.5 IPL Change when Interrupt Request is Acknowledged
When a peripheral function interrupt request is acknowledged, IPL sets the priority level for the acknowl-
edged interrupt.
Software interrupts and special interrupts have no interrupt priority level. If an interrupt request that has
no interrupt priority level is acknowledged, the value shown in Table 11.5 is set in IPL as the interrupt
priority level.
