Machine Procedure CLOCK and Information TRANSITIONS: The SDA pin is generally pulled significant having an exter-nal unit. Information within the SDA pin might transform only for the duration of SCL lower time intervals (refer toData Validity timing diagram).
Details variations during SCL high periods will suggest a startor cease problem as defined under.Begin Issue: A high-to-low transition of SDA with SCL higher is a start conditionwhich have to precede any other command (make reference to Start and End Definition timingdiagram).
Quit Ailment: A low-to-high transition of SDA with SCL substantial is a quit issue.Following a read sequence, the prevent command will put the EEPROM in a very standby powermode (consult with Commence and Quit Definition timing diagram).
Admit: All addresses and facts words and phrases are serially transmitted to and from theEEPROM in 8-bit phrases.
The EEPROM sends a zero to acknowledge that it hasreceived each and every term. This transpires throughout the ninth clock cycle.STANDBY Mode: The AT24C01A/02/04/08/16 options a low-power standby modewhich is enabled: (a) upon power-up and (b) following the receipt in the Halt little bit and thecompletion of any inner operations.
MEMORY RESET: Just after an interruption in protocol, electricity decline or technique reset, any 2-wire element is usually reset by pursuing these techniques:1. Clock up to nine cycles.2. Glance for SDA substantial in just about every cycle when SCL is high.three. Produce a start condition.
