10.5.2
If a timer counter clock pulse is generated during the T2 state of a TCNT write cycle, the write
takes priority and the timer counter is not incremented. Figure 10.7 shows this operation.
10.5.3
If bits CKS2 to CKS0 in TCSR are written to while the WDT is operating, errors could occur in
the incrementation. Software must stop the watchdog timer (by clearing the TME bit to 0) before
changing the values of bits CKS2 to CKS0.
10.5.4
If the mode is switched from watchdog timer to interval timer, while the WDT is operating, errors
could occur in the incrementation. Software must stop the watchdog timer (by clearing the TME
bit to 0) before switching the mode.
