Rise and Fall time specifications for SCL and SDA lines of I2C

Version 1
    Answer:

    Question: What are the Rise and Fall time specifications for SCL and SDA lines of I2C communication in PSoC device?

    Response: The PSoC is fully compliant to the Philips I2C bus standard which may be downloaded from the below link. 

     http://www.nxp.com/acrobat_download/literature/9398/39340011.pdf

    The following table shows the rise and fall time specifications for both SCL and SDA lines in both Full speed and Standard speed of operation.
