Master Operation in 7-Bit Addressing Modes

In Master 7-bit Addressing modes, the slave’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 master wishes to read data from the slave, software must set the R/W bit (R/W = 1). When the master wishes to write data to the slave, software must clear the R/W bit (R/W = 0).
