11.1
The H8/3337 Series and H8/3397 Series have an on-chip watchdog timer (WDT) that can monitor
system operation by resetting the CPU or generating a nonmaskable interrupt if a system crash
allows the timer count to overflow.
When this watchdog function is not needed, the watchdog timer module can be used as an interval
timer. In interval timer mode, it requests an WOVF interrupt at each counter overflow.
11.1.1
WDT features are shown below.
Selection of eight counter input clocks
Switchable between watchdog timer mode and interval timer mode
Timer counter overflow generates an internal reset or internal interrupt:
Selection of internal reset or internal interrupt generation in watchdog timer mode
WOVF interrupt request in interval timer mode
