16.3.4 Selecting WDT Period

The WDT can be configured for various time-out periods by controlling the WDT postscaler value. The settings are chosen using the WDTPSR[4:0] inputs for the Run Mode Counter and the WDTPSS[4:0] inputs for the Sleep Mode Counter. These values range from 1 to 2^20 and allow for time-out periods of from 1 ms to over 17 minutes when using the 21 kHz LPRC clock.
