Hi,

It's not clear what information you are looking for.

Basically:
* by writing it's registers
* with values explained in the datasheet

I trying to configure by register.
first i crash my code using Divide by zero fault. then my code stuck in UsageFault.
so, code will be crash at that time window watchdog timer should reset the my code.

RCC->APB1ENR |= (1<<11); // Window watchdog clock enable

WWDG->CFR = 0x0000014f; // 10: CK Counter Clock (PCLK1 div 4096) div 4 & window value is 79
WWDG->CR = 0x0000006C;
WWDG->CR |= WWDG_CR_WDGA;

but code is looping the above three line
