The datasheet exactly tells:
MEMORY RESET: After an interruption in protocol, power loss or system reset, any 2-wire part can be reset by following these steps: 1. Clock up to 9 cycles. 2. Look for SDA high in each cycle while SCL is high. 3. Create a start condition as SDA is high. Link to this datasheet is: http://www.datasheetcatalog.com/datasheets_pdf/A/T/2/4/AT24CXX.shtml Another Datasheet AT24C02B tells: 2-Wire Software Reset: After an interruption in protocol, power loss or system reset, any 2-wire part can be reset by following these steps: (a) Create a start bit condition, (b) clock 9 cycles, (c)create another start bit followed by stop bit condition as shown below. The device is ready fornext communication after above steps have been completed. Link to this datasheet is: http://www.atmel.com/dyn/resources/prod_documents/doc8517.pdf |
