The I2C mode supports 7-bit and 10-bit addressing modes.
7-Bit Addressing
In the 7-bit addressing format (see Figure 38-5), the first byte is the 7-bit slave address and the R/W bit. The ACK bit is sent from the receiver after each byte.
10-Bit Addressing
In the 10-bit addressing format (see Figure 38-6), the first byte is made up of 11110b plus the two MSBs of the 10-bit slave address and the R/W bit. The ACK bit is sent from the receiver after each byte. The next byte is the remaining eight bits of the 10-bit slave address, followed by the ACK bit and the 8-bit data. See I2C Slave 10-bit Addressing Mode and I2C Master 10-bit Addressing Mode for details on how to use the 10-bit addressing mode with the USCI module.
