33. Watchdog Timer

When the emulator is connected to operate the watchdog timer (WDT) during using the
H8S/2377F and H8S/2367F, the WDT continues operation during a break.

•

When a counter value overflows during a break in the watchdog timer mode:

An internal reset signal is generated when the internal LSI is reset.

•

When a counter value overflows during a break in the interval timer mode:

An interrupt request is generated, but it is suspended during a break.
