8.3.1.2 Test Mode
This commands configures the watchdog‘s test mode. In test mode the watchdog operates nor-
mally, but does not actually perform a module reset. Instead, it signals the (simulated) reset via
the LED by flashing the green ON LED two times to visualize the watchdog trigger. Entering
the test mode disables the actual watchdog functionality.
8.3.1.3 Repetitive Module Reset
This command configures a repetitive module resets, if the watchdog is enabled. The param-
eter sets the RST_REP timeout value. If the watchdog is enabled, an unconditional module re-
set every RST_REP milliseconds is performed.
Changing this configuration disables the watchdog. The feature becomes active, if the watch-
dog is enabled again, and after the MIN_START_TIME has passed.
For normal operation, this value should be set to a value greater than 30 minutes, some use
cases may even require a setting > 24h.
