Host Operation in 7-Bit Addressing Modes

In Host 7-bit Addressing modes, the client’s 7-bit address and R/W bit value are loaded into either I2CxADB1 or I2CxTXB, depending on the Address Buffer Disable (ABD) bit setting. When the host wishes to read data from the client, software must set the R/W bit (R/W = 1). When the host wishes to write data to the client, software must clear the R/W bit (R/W = 0).
