Appendix A Programming the Watchdog Timer 59

Programming the

Watchdog Timer

The PCA-6144V 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.
