CHAPTER 2: POWER SUPPLY AND INITIAL RESET
Further, the time authorize circuit can be selected with the mask option. The time authorize circuit
performs initial reset, when the input time of the simultaneous high input is authorized and found to be
the same or more than the defined time (1 to 2 sec).
If you use this function, make sure that the specified ports do not go high at the same time during
ordinary operation.
2.2.4 Watchdog timer
If the CPU runs away for some reason, the watchdog timer will detect this situation and output an initial
reset signal. See Section 4.2, "Resetting Watchdog Timer", for details.
2.2.5 Internal register at initial reset
Initial reset initializes the CPU as shown in the table below.
