Hello Experts,
I just wanted to get a confirmation from you on the timing analysis done based on the Prescaler and Pre-Divider for the Watchdog clock. Attached the excel sheet used for the Watcdog clock configuration.xlsxcalculation
please let me know if my assumption is correct.
Per the calculation, I believe the calculated time is the watchdog time out value before which it needs to be refreshed.
