12.4
12.4.1
If a timer counter clock pulse is generated during the T3 state of a write cycle to the TCNT, the
write takes priority and the timer counter is not incremented (figure 12.8).
12.4.2
If the values of bits CKS2–CKS0 are altered while the WDT is running, the count may increment
incorrectly. Always stop the watchdog timer (by clearing the TME bit to 0) before changing the
values of bits CKS2–CKS0.
12.4.3
To prevent incorrect operation, always stop the watchdog timer (by clearing the TME bit to 0)
before switching between interval timer mode and watchdog timer mode.
