Appendix A Programming the Watchdog Timer 33

A

Programming the
Watchdog Timer

The PCA-6151 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 standalone and unmanned
environments.
