Bit 7âWatchdog 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 H8/3003
chip internally. If bit RSTOE is set to 1, this reset signal is also output (low) at the RESO pin to
initialize external system devices.
Bit 7

0
1
Description
[Clearing condition]
Cleared to 0 by reset signal input at RES pin, or by writing 0
(Initial value)
[Setting condition]
Set when TCNT overflow generates a reset signal during watchdog timer operation
Bit 6âReset Output Enable (RSTOE): Enables or disables external output at the RESO pin of
the reset signal generated if TCNT overflows during watchdog timer operation.
Bit 6
RSTOE Description
0
Reset signal is not output externally
1
Reset signal is output externally
(Initial value)
