Watchdog information
This 16-bits register specifies the time in milliseconds to watchdog reset. If module does
not receive any valid message within that time, all Digital and Analog Outputs will be set to
the default state.
This feature is useful if there is an interruption in data transmission and for security
reasons. Output states must be set to the appropriate state in order to reassure the safety
of persons or property.
The default value is 0 milliseconds which means the watchdog function is disabled.
