Question about TMS320F28069 watchdog timer period



Hello, I have a question about watchdog timer period.

I read SPRUH18–April 2011page 98-103.

Can someone confirm the watchdog timer period formula ?

 

WDG PERIOD = 512*256*2^(WDPS-1)/10 us

where

WDG PERIOD = watchdog period

WDPS = watchdog prescaler

 

Here the table

WDPS ms
1 13,1
2 26,2
3 52,4
4 104,9
5 209,7
6 419,4
7 838,9

 

Thanks in advice.
