- Sets Hardware WDT timer
- for stalled processor situations, generates a reset
- 62ms upto 16 seconds response
- Sets Software WDT using EarlyWarning timer (EWT) and software counter (Global Variable)
- for stalled software, generates a reset if software loop does not clear WDT on time
- Total soft-WDT intervals are 8,16,32 Seconds ,1,2,4,8.16 Minutes
- V1.3.0 - added shutdown function for soft-watchdog : now possible to do an extra job before shutting down like saving your key data *thnks to Juraj
