20.2.2.5 Repeated Start

The client EEPROM has the required address information that is required to return the requested data byte to the host. However, the R/W status bit from the first device address byte specifies the host transmission and the client reception. The direction of the bus must be reversed for the client to send data to the host.

To perform this function without ending the message, the host sends a Repeated Start. The Repeated Start is followed with a device address byte containing the same device address as before, and with R/W = 1, to indicate the client transmission and the host reception.
