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

 

The PSoC is fully compliant to the Philips I2C bus standard which may be downloaded from the following link: Download

The following Table 1 shows the Rise and Fall Time specifications for both SCL and SDA lines in both Full speed and Standard speed of operation.
