Operation
1. Start Condition
When the SCL line is “H” the SDA line changes from “H” to “L”. This allows the device to go to the start
condition.
All operations begin from the start condition.
2. Stop Condition
When the SCL line is “H” the SDA line changes from “L” to “H”. This allows the device to go to the stop
condition.
When the device receives the stop condition signal during a read sequence, the read operation is interrupted,
and the device goes to standby mode.
When the device receives the stop condition signal during write sequence, the retrieval of write data is halted,
and the EEPROM initiates rewrite.
3. Data Transmission
Changing the SDA line while the SCL line is “L” allows the data to be transmitted. A start or stop condition is
recognized when the SDA line changes while the SCL line is “H”.
