I2C Bus Clock Register (ICCR2)?? Help

I want to use a 400kHz I2C bus with my ST72321.

The datasheet shows I2CCCR values for a 4MHz and 8MHz clock, but does not have values for a 16MHz clock, nor can I find a formula or correlation in the data that would explain the values in the table in the datasheet.

Does anyone know what I should set I2CCCR to for 400kHz when I am using a clock of 16MHz?

Or perhaps the formula so I can set it up?

Thanks!
