Note : The MB3793 watchdog timer monitors Clock1 (CK1) and Clock2 (CK2) pulses alternately.
When a CK2 pulse is detected after detecting a CK1 pulse, the monitoring time setting capacity (C_TW)
switches to charging from discharging.
When two consecutive pulses occur on one side of this alternation before switching, the second pulse
is ignored.
In the above figure, pulse *1 and *2 are ignored.
