Hi,
We are using FS6500 in out project application. Could you please let me know the timing parameters of watchdog signal. Is it entirely software configurable?
If the duty cycle is not 50% then how will be the window period duration looks like when compared to "Table 18. WD_WINDOW". For example, if we set 0011b in WD_WINDOW then the Window period duration can be as low as 2.7ms and as high as 3.3ms when duty cycle is not 50%. In this case does the OPEN & CLOSED windows is still equally divided? A bit confused with the FS CLK accuracy image it seems like the red and blue period is having equal open & closed window period.
Thank you Tomas!
Could you please let me know the following data :
1. Time taken by the watchdog timer to detect a rising and falling edge
2. Reset time and reset cycle duration
Hi Anne,
The Watchdog Window Period is configurable by SW. Not only during the INIT_FS phase (first 256ms after RSTB is released), but also later during the Normal mode.
By default, WD Window duration is 3ms which is in alignment with an FTTI below 10ms.
The Watchdog Window Duty Cycle is set to 50% ±10% and is not modifiable.
Best regards,
Tomas
