Appendix A Programming the Watchdog Timer 99

Programming the

Watchdog Timer

The mainboard is equipped with a
watchdog timer that resets the CPU or
generates an interrupt if processing comes
to a standstill for whatever reason. This
feature ensures system reliability in
industrial stand-alone and unmanned
environments.
