how to used the watchdog counter in ADAU1452

hello, I want to set the "watchdog counter" to check if an errors would occus that the program does not finish intime for the next incoming sample.

Here is my setting in SigmaStudio(V4.1):

In the datasheet of ADAU1452(rev.c), it references that the number of "watchdog maxcounter" should be sightly larger than the maximum number of instructions expected to execute in the program.

however,I find that the watchdog do not works. no matter what value of "watchdog maxcounter" I set, the watchdog error flag is not raised in the panic manager. (e.x I set "watchdog maxcounter" is "1", then compile and download the code using the USBi , and then click the button of "Read All Registers" ).

is my setting not right?
