I have stm32H74Zi chip and is running in 64Mhz clock speed and have scaled down the speed to 32Mhz for APB1 (I2C peripheral) using clock divider. Want to know how TIMINGR value is working with both the frequencies (32 and 64Mhz at APB1 peripheral).

Using clock divider(/2) scaled down the APB1 peripheral clock speed to 32Mhz. Now I have different TIMINGR values for for each of 32 and 64MHz clock speed at APB1. I tried 32MHz TIMINGR value for 64MHz clock speed and it worked.I want to know how the...
