- This watchdog timer WDT periodically resets the watchdog timer WDT so that no error signal is generated when the microcomputer 49 is operating normally. However, the microcomputer 49 has malfunctioned. In this case, the above-mentioned periodic watchdog timer WDT is not reset and an error signal is output to stop it by operating a safety device.
- Watchdog timer The WDT timer value is set to 1000 ms, for example, in the initial stage when the microcomputer 49 is turned on. Since the watchdog timer is a well-known technique, its description is omitted here.
