The SDA pin is generally pulled large by having an exter-nal gadget. Knowledge to the SDA pin may adjust only all through SCL lower time durations.

Details variations in the course of SCL large durations will point out a get started or end ailment asdefined beneath.Knowledge ValiditySTART Ailment: A high-to-low changeover of SDA with SCL higher is actually a commence conditionthat need to precede every other command.

Get started and Prevent DefinitionSTOP Problem: A low-to-high changeover of SDA with SCL higher is really a prevent problem.Following a read through sequence, the quit command will place the EEPROM inside a standby powermode .Admit: All addresses and facts words and phrases are serially transmitted to and fromthe EEPROM in 8-bit terms.

The EEPROM sends a “0” to accept that it hasreceived each and every term. This transpires during the ninth clock cycle.STANDBY Manner: The AT24C02A/04A/08A/16A characteristics a low-power standby modethat is enabled: (a) on power-up and (b) following the receipt of your Cease little bit as well as com-pletion of any internal operations.

Soon after an interruption in protocol, energy decline or process reset, anytwo-wire component may be reset by pursuing these steps: one. Clock around nine cycles2. Appear for SDA large in each individual cycle while SCL is high3. Develop a start condition as SDA is substantial.
