A microcomputer or microcontroller with a watchdog timer-counter also has an external reset signal generator. When the central processing unit of the microcomputer or microcontroller fails to execute its control program correctly, the watchdog timer-counter generates an internal reset signal for a first interval, resetting the central processing unit, and the external reset signal generator generates an external reset signal for a second interval, different from the first interval. The length of the second interval can be set to match the requirements of external peripheral devices to which the external reset signal is supplied. |
