Section 18 Watchdog Timer (WDT)
(2)
These registers can be read from in the same way as other registers. For reading, TCSR is assigned
to address H'FFA4, TCNT to address H'FFA5, and RSTCSR to address H'FFA7.
18.6.2
If a TCNT clock pulse is generated during the T2 cycle of a TCNT write cycle, the write takes
priority and the timer counter is not incremented. Figure 18.5 shows this operation.
18.6.3
If bits CKS2 to CKS0 in TCSR are written to while the WDT is operating, errors could occur in
the incrementation. The watchdog timer must be stopped (by clearing the TME bit to 0) before the
values of bits CKS2 to CKS0 are changed.
18.6.4
If the timer mode is switched from watchdog timer mode to interval timer mode while the WDT is
operating, errors could occur in the incrementation. The watchdog timer must be stopped (by
clearing the TME bit to 0) before switching the timer mode.
