Parameters
This parameter is ensured by characterization and not 100% tested.
This specification is not a part of the I
plus SDA Fall (or rise) time:
If this parameter is too short, it can create an unintended Start or Stop condition to other devices on the bus line. If this
parameter is too long, Clock Low time (T
For Data Input: If this parameter is too long, the Data Input Setup (T
For Data Output: This parameter is characterized, and tested indirectly by testing T
