SBC Watchdog disable while reprogramming

[Shailendrag]

Hi 

I have following hardware configuration FS6523C and AURIX 387, in which I have to disable the SBC watchdog while reprogramming (jump from Application to bootloader).  

My question: How to disable the watchdog when system is in active state as we know we can disable the watchdog in INIT_FS mode only.

Thanks

2. By reset we can enter into INIT_FS state, and then we have to disable the watchdog by writing WD_WINDOW_3:0 = 0000. Is my understanding is correct ?

For the first watchdog refresh please read datasheet page42 Rev7.0-12.5.2.1 Normal operation (first watchdog refresh)

1: enter debug mode to disable watchdog.

2: disable watchdog by enter INIT_FS -- INIT_FS can be entered by a reset request with RSTB_REQ bit in SF_OUTPUT_REQUEST register.
