12.4.4 Setting watchdog timer interval interrupt
generated when 75% of the overflow time is reached.
R01UH0106EJ0300 Rev.3.00
Oct 01, 2010
Depending on the setting of bit 7 (WDTINT) of an option byte (000C0H), an interval interrupt (INTWDTI) can be

operating after the oscillation stabilization time has elapsed.
Therefore, if the period between the STOP mode release and the watchdog timer overflow is short, an
overflow occurs during the oscillation stabilization time, causing a reset.
Consequently, set the overflow time in consideration of the oscillation stabilization time when
operating with the X1 oscillation clock and when the watchdog timer is to be cleared after the STOP
mode release by an interval interrupt.
watchdog timer enable register (WDTE)). If ACH is not written to the WDTE register before the overflow time,
an internal reset signal is generated.
Interval interrupt is used.
Interval interrupt is generated when 75% of overflow time is reached.
