14.4.3
When TCNT overflows in watchdog timer mode, the OVF bit in TCSR is set to 1. When the
RST/NMI bit is 1 here, the internal reset signal is generated for the entire LSI. At the same time,
the low level signal is output from the RESO pin. The timing is shown in figure 14.5.
14.5
During interval timer mode operation, an overflow generates an interval timer interrupt (WOVI).
The interval timer interrupt is requested whenever the OVF flag is set to 1 in TCSR. OVF must be
cleared to 0 in the interrupt handling routine.
When the NMI interrupt request is selected in watchdog timer mode, an NMI interrupt request is
generated by an overflow.
