STM32F3: help with I2C_InitStructure.I2C_Timing

Question asked by constant.colin on Feb 12, 2015
Hi,
I wonder if someone can help me understand how to select a value for I2C_InitStructure.I2C_Timing.  I'm using the value from the demo and it works; I just have no idea how it is arrived at:

I2C_InitStructure.I2C_Timing = 0x00902025;

I've read the section in the Reference Manual but I'm afraid I am no wiser.
Thanks for your time,
Colin
