Watchdog timers are essential in remote, automated systems such as this Mars Exploration Rover. Watchdog timers are commonly found in embedded systems and other computer-controlled equipment where humans cannot easily access the equipment or would be unable to react to faults in a timely manner.
The Command Loss Timer Reset can be used for computer system rebooting, but only when multiple timers have not been reset—like the classical "Dead man's switch" of industrial transport use. Embedded systems need to be inherently self-reliant, as this is fundamentally part of their design.

Watchdog Timer support – Watchdog is a software timer that triggers a system reset action if the system hangs on crucial faults for an extended period of time. The watchdog mechanism can bring the system back from the nonresponsive state into normal operation by waiting until the timer goes off and subsequently rebooting the device.

A digital signal controller (DSC) is a hybrid of microcontrollers and digital signal processors (DSPs). Like microcontrollers, DSCs have fast interrupt responses, offer control-oriented peripherals like PWMs and watchdog timers, and are usually programmed using the C programming language, although they can be programmed using the device's native assembly language.
