5.3 Description of Operation
With the exception of the watchdog timer interrupt (WDTINT), interrupt enable/disable for 20 sources is controlled by
the master interrupt enable flag (MIE) and the individual interrupt enable registers (IE1 to 7). WDTINT is a
non-maskable interrupt.
When the interrupt conditions are satisfied, the CPU calls a branching destination address from the vector table
determined for each interrupt source and the interrupt shift cycle starts to branch to the interrupt processing routine.
Table 5-1 lists the interrupt sources.
Note:
- When multiple interrupts are generated concurrently, the interrupts are serviced according to this priority and
processing of low-priority interrupts is pending.
- Please define vector tables for all unused interrupts for fail safe.
