12.3.3 Timing of Setting of Overflow Flag (OVF)
Figure 12-6 shows the timing of setting of the OVF flag in TCSR. The OVF flag is set to 1 when
TCNT overflows. At the same time, a reset signal is generated in watchdog timer operation, or an
interval timer interrupt is generated in interval timer operation.
