16.3.2 Reset operation by watchdog timer (WDT) overflow (WDTRES)
(WDTRES signal generation), a system reset is executed and the hardware is initialized to the initial status.
the reset status is then automatically released. Following reset release, the CPU starts program execution after
securing the oscillation stabilization time (initial value of OSTS register: 2
the RESET pin (see 16.3.1 Reset operation via RESET pin).

When the watchdog timer is set to the reset operation mode due to overflow, upon watchdog timer overflow
Following watchdog timer overflow, the reset status is entered and lasts the predetermined time (analog delay), and
The oscillator is stopped during the reset period, so secure the oscillation stabilization time.
The status of each hardware during the reset period and after reset release is the same as the reset operation by
