Section 14 Watchdog Timer (WDT)
14.4.3
1. Set the WT/IT bit in WTCSR to 1, the type of count clock in the CKS[2:0] bits in WTCSR,
2. Set the TME bit in WTCSR to 1 to start the count in watchdog timer mode.
3. While operating in watchdog timer mode, rewrite the counter periodically to H'00 to prevent
4. When the counter overflows, the WDT sets the WOVF flag in WRCSR to 1, and the
5. If the RSTE bit in WRCSR is set to 1, a signal to reset the inside of this LSI can be generated
6. When a WDT overflow reset is generated simultaneously with a reset input on the RES pin,
