CYC
)
(11) Watchdog timer
- The watchdog timer period set by external RC.
- Watchdog timer can be set to produce interrupt, system reset
(12) Interrupts
- 29-source, 10-vectored interrupts:
1. Three level (low, high and highest) multiple interrupts are supported. During interrupt handling,
an equal or lower level interrupt request is refused.
2. If interrupt requests to two or more vector addresses occur at once, the higher level interrupt
takes precedence. In the case of equal priority levels, the vector with the lowest address takes
precedence.
No.

HOLD mode is used to reduce the power dissipation. Both program execution and peripheral circuits
are stopped.
