WDTZero.h - Library for Watchdog on the SAM D Zero Series
See ATSAMD2x datasheet, #18, page205 onwards
Defines Watchdog Calss to Setup Watchdog timer in Normal mode with EarlyWarning interrupt.
1. Sets Hardware WDT timer
- -> for stalled processor situations, generates a reset
- -> 4, 8 or 16 seconds response
2. 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
- -> EWT runs on 0.5 Sec interval ISR
- -> Total soft-WDT intervals are 4, 8, 6, 32 Seconds, 1, 2, 4, 10 Minutes
