7. Device Operation

Clock and Data Transitions: The SDA pin is normally pulled high with an external device. Data on the SDA pin

may change only during SCL low time periods. Data changes during SCL high periods will indicate a Start or

Stop condition as defined below.

Start Condition: A high-to-low transition of SDA with SCL high is a Start condition which must precede any

other command.

Stop Condition: A low-to-high transition of SDA with SCL high is a Stop condition. After a read sequence, the

Stop command will place the EEPROM in a standby power mode.
