Section 13 Watchdog Timer
13.5.5
Internal Reset in Watchdog Timer Mode
The chip is not reset internally if TCNT overflows while the RSTE bit is cleared to 0 during
watchdog timer operation, but TCNT and TCSR of the WDT are reset.
TCNT, TCSR, and RSTCSR cannot be written to while the WDTOVF signal is low. Also note
that a read of the WOVF flag is not recognized during this period. To clear the WOVF flag,
therefore, read RSTCSR after the WDTOVF signal goes high, then write 0 to the WOVF flag.
