9.6.2
If a timer counter increment clock pulse is generated during the T3 state of a write cycle to TCNT,
the write takes priority and the timer counter is not incremented. Figure 9.8 shows this operation.
9.6.3
If the values of bits CKS2 to CKS0 in the timer control/status register (TCSR) are rewritten while
the WDT is running, the count may not increment correctly. Always stop the watchdog timer (by
clearing the TME bit to 0) before rewriting the values of bits CKS2 to CKS0.
9.6.4
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.
