request is generated. When a watchdog timer reset request is generated, the
nal and the internal hardware is reset. The reset time is maximum 24/fc [s] (1.5 µs @ fc = 16.0 MHz).
When a binary-counter overflow occurs while WDTCR1<WDTOUT> is set to “1”, a watchdog timer reset
Note:When a watchdog timer reset is generated in the SLOW1 mode, the reset time is maximum 24/fc (high-fre-
quency clock) since the high-frequency clock oscillator is restarted. However, when crystals have inaccura-
cies upon start of the high-frequency clock oscillator, the reset time should be considered as an approximate
value because it has slight errors.
