How much time require for independent watchdog to be ready on stm32f765ni mcu?

After enabling independent watchdog(IWDG) and write access, I am setting prescaler and reload counter and then waiting for IWDG_SR register to be 0x00000000. Waiting period is taking approx 48 milliseconds, but as per datasheet it should take five RC 40khz cycles. window option is disable.

Hello @DC303132,

Can you tell me more about your setting? What are the values of the prescaler and the reloading counter?
