MPC574x SWT issue

Dear NXP,

I'm using MPC5744p SWT with S32 ds IDE.

I have referenced the sample code "Example MPC5744P SWT Short reset GHS614".

There are some functions were used in my project, such as following:
void main()
/*Clock configuration and mode transition to RUN0*/

/*Clear faults in FCCU*/

/*Configure FCCU for SWT reset reaction*/

/*Initialize and start SWT*/

The SWT fails works when system run into SWT_Init() and implement "SWT_0.SR.R = 0xC520;".
I used to step over (in debug mode) and free run mode (not in debug mode), respectively.
It always shows "IVOR1_Vector() at 0x1001010" when implement "SWT_0.SR.R = 0xC520;".

I have encountered this problem before when the clock source doesn't enable when writing ADC register.

Does this same as clock issue?

Please help me thank you.
