/**
 * YWatchdog Class: watchdog control interface, available for instance in the Yocto-WatchdogDC
 *
 * The YWatchdog class allows you to drive a Yoctopuce watchdog.
 * A watchdog works like a relay, with an extra timer that can automatically
 * trigger a brief power cycle to an appliance after a preset delay, to force this
 * appliance to reset if a problem occurs. During normal use, the watchdog timer
 * is reset periodically by the application to prevent the automated power cycle.
 * Whenever the application dies, the watchdog will automatically trigger the power cycle.
 * The watchdog can also be driven directly with pulse and delayedPulse
 * methods to switch off an appliance for a given duration.
