      Hi

       

      I have a question about FX3's IIC.

      I want to set IIC speed to 1Mhz.
      I try after setting as below but IIC speed is about 760 Khz.

      1. Set VIO5 to 3.3 V.
      2. Set CyU3PI2cSetConfig funciton with bitrate 1000000.

      3. Set CyU3PSetI2cDriveStrength function with CY_U3P_DS_FULL_STRENGTH.

       

      Is there need any other setting?
