1. STTS2002 will not initiate clock stretching which is an I2C bus optional feature.
2. Guaranteed by design and characterization, not necessarily tested.
3. For a restart condition, or following a WRITE cycle.
4. This parameter reflects maximum WRITE time for EEPROM.
5. Bus timeout value supported depends on setting of TMOUT bit 6 in capability register.
