Parameters
This parameter is ensured by characterization and is not 100% tested.
After a Repeated Start condition or an Acknowledge bit.
If this parameter is too short, it can create an unintentional Start or Stop condition to other devices on the I
this parameter is too long, the Data Input Setup (T
Data Input: This parameter must be longer than t
Data Output: This parameter is characterized, and tested indirectly by testing T
