I2C clock frequency of CapSense Exress device

Version 1
    Question: What is the frequency at which I2C slave is configured in CapSense Express devices?



    I2C slave in CapSense Express devices is configured at 400KHz but as per the I2C spec, the I2C bus works at the speed of the slowest device on the bus. So, if the master is sending data at a rate of 50KHz or 100KHz then the CapSense express I2C will work at a rate of 50KHz or 100Khz only.
