To benefit from the window watchdog feature and help the watchdog timer monitor the software execution more closely, TI recommends that the watchdog be set and reset at different points in the program rather than pulsing the watchdog input periodically by using the prescaler of a microcontroller or DSP. Furthermore, the watchdog trigger pulses should be set to different timings inside the window frame to release a defined reset if the program should hang in any subroutine. This setting allows the window watchdog to detect timeouts of the trigger pulse as well as pulses that distort the lower boundary.
