watchdog: Repetitive module reset, UART reset, GPIO reset, Restart delay and Always on.
With these commands the new configuration setting becomes effective only after the hardware
watchdog is enabled again.
8.3.1.1
Watchdog On/Off
This command is used to enable or disable the watchdog function. When disabled, all timers
are stopped and the watchdog doesn't perform a module reset. When enabled, all configured
timers start after a delay time of MIN_START_TIME. If MIN_START_TIME=0, all reset timers
start immediately. Also, when the watchdog is enabled and ALWAYS_ON>0, the watchdog ob-
serves the modules on/off state, and starts the module in case it detects that the module is off.
