frequency of I2C of KL25Z

[xiaocongfu]

Hello, I'm using the interface I2C of KL25Z128VLK4 to generate a phase sinusoid. I need a frequency of 750kHz, but when the SCL frequency exceed 100kHz, I have a warning: the device is designed to operate up to 100kHz. So I'd like to know the limite maximun of the frequency of I2C of KL25Z.

PS: I have already tried to use a frequency up to 100kHz, but my output can't increase according to this frequency.

Thank your for your answers!
