Section 14 Watchdog Timer (WDT)
14.6.2
If a timer counter clock pulse is generated during the next cycle after the T
cycle, the write takes priority and the timer counter is not incremented. Figure 14.5 shows this
operation.
14.6.3
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 value of bits CKS2 to CKS0.
14.6.4
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.
