AURIX SCU_WDT:how to really enable the WDTCPU0 in debug mode?

[oneday]

When using the code example to test SCU_WDT(in debug mode ), there are some question as follows:

when execute code line 61:   IfxScuWdt_serviceCpuWatchdog(IfxScuWdt_getCpuWatchdogPassword()); /* Service the CPU0WDT */,then use the "printf"  to print the REG "SCU_WDTCPU0SR" , the value of "SCU_WDTCPU0SR" shows as follows:

I think the WDTCPU0 is not really enabled,because the SCU_WDTCPU0SR.B.TIM = 0xFFFC and this value has never changed.

so,  how to  really enable  the  WDTCPU0 in debug mode?  

Looking forward to your reply.

Generally, FFFCh is counted up to FFFFh and then timeout, that means only 4 clocks to be expired, in this short window,  the user could do some operations.
