I2C Timing Calculation

Hi Everyone,

I am working on I2C to sense DAC data. I generated the code using STM32CubeMX. It gives timing in hex format i.e.

'hi2c2.Init.Timing = 0x10707DBC;'. It does confuse me that how does it calculate timing ? 

I don't know the formula behind this timing value. I need to know it to setup my own timing.

Regards,

Manish
