Bit 7—Watchdog Timer Reset (WRST): During watchdog timer operation, this bit indicates that
TCNT has overflowed and generated a reset signal. This reset signal resets the entire H8/3024 chip
internally. If bit RSTOE is set to 1, this reset signal is also output (low) at the
initialize external system devices. Note that there is no
flash memory.
Bit 6—Reset Output Enable (RSTOE): Enables or disables external output at the
the reset signal generated if TCNT overflows during watchdog timer operation. Note that there is
no
