13.6.2
If a timer counter clock pulse is generated during the T
takes priority and the timer counter is not incremented. Figure 13.7 shows this operation.
13.6.3
If CKS2 to CKS0 bits 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 CKS2 to CKS0 bits.
13.6.4
If the PSS bit in TCSR_1 is written to while the WDT is operating, errors could occur in the
operation. Stop the watchdog timer (by clearing the TME bit to 0) before changing the values of
PSS bit.
