detailed description
watchdog
In a microprocessor- or DSP-based system, it is not only important to supervise the supply voltage, it is also important
to ensure correct program execution. The task of a watchdog is to ensure that the program is not stalled in an indefinite
loop. The microprocessor, microcontroller, or DSP has to typically toggle the watchdog input within 0.8 s to avoid a
time out occurring. Either a low-to-high or a high-to-low transition resets the internal watchdog timer. If the input is
unconnected or tied with a high impedance driver, the watchdog is disabled and will be retriggered internally.
