5.3
With the exception of the watchdog timer interrupt (WDTINT) and the NMI interrupt (NMINT), interrupt
enable/disable for 27 sources is controlled by the master interrupt enable flag (MIE) and the individual interrupt enable
registers (IE1 to 7). WDTINT and NMIINT are non-maskable interrupts.
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.
