Operation Start Condition When line "H," line changes from "L." This allows device start condition. operations begin from start condition. Stop Condition When line "H," line changes from "H." This allows device stop condition. When device receives stop condition signal during read sequence, read operation interrupted, device goes standby mode. When device receives stop condition signal during write sequence, retrieval write data halted, EEPROM initiates rewrite.

Acknowledgment Polling Acknowledgment polling used know when rewriting EEPROM finished. After EEPROM receives stop condition signal once starts rewrite, operations prohibited. Also, EEPROM cannot respond signal transmitted master device. Accordingly, master device transmits start condition signal device address read/write instruction code EEPROM (namely, slave device) detect response slave device. This allows users know when rewriting EEPROM finished. That slave device does output acknowledgment signal, means that EEPROM rewriting; when slave device outputs acknowledgment signal, know that rewriting been completed. recommended read instruction read/write instruction code transmitted master device.
