„ 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."
