Hello Support,
According to the following post :
http://e2e.ti.com/support/microcontrollers/hercules/f/312/t/210338.aspx
The Period of Watchdog is determined by the TIME INSTANT when CPU Services the Wacthdog with "write A35C to WDKEY".
Usually the Period of Windowed Watachdog should be independent of CPU Service Instant of Watchdog.
If you look at TI following document -- slvsab1d.pdf -- for TPS7A6333 device http://www.ti.com/litv/pdf/slvsab1d
related to "Figure 24. Watchdog Window Duration" in Page 15, you will see Watchdog Period is constant irrespective of CPU timing of Service.
In effect, is there any useful way current Digital Window Watchdog be used at all because the Period END Point will be shifting with the instant when CPU services the Watchdog.
Any clue about the expected usage of Digital Window Watchdog in comparison to slvsab1d.pdf based architecture will be helpful.
Thank you.
Regards
Pashan
