Hi all, I'm working on I2c Peripheral and can see that IDE auto generates i2c timing values. But I still want to know how that value can be converted into Frequency(Hertz) in detail. Please do feel free to provide some information or any reference links.

Look in the reference manual for your chip. It is explained in detail. It is different for different chip families. Due to clock stretching, the clock behavior can be nontrivial to understand.

Please include the chip number in your post.

Chip number is STM32H743ZIT6U.

I just want to know the direct conversion formulas of Timing to Hertz, if you can please.
