Jul 28, 2014 · There is also a “window watchdog” (WWDT) which requires the code to tickle it frequently, but not too often. This is a very effective way to insure crashed code that randomly writes to the protection mechanism does not cause a WDT tickle, and the WWDT can generate an interrupt shortly before reset is asserted.

I'm playing around with the settings for the windowed watch dog timer (WWDT) for the PIC18F24K40.. In chapter 3.7.3 (page 37) about device configuration, the DT Window Select bits are briefly described, but there is no explanation in chapter 9 …

Set the 0th bit in WDTCON register. WDTCON.0 = 1. The rest of the bits in WDTCON let you configure this peripheral, see datasheet for more brief notes.
