The I2C controller operates in 8-bit word data format (byte write access supported for the last access). Each byte transmitted or received on the serial data line is 8 bits long. The number of bytes that can be transmitted or received is not restricted. The data is transferred with the most-significant bit (MSB) first. In receiver mode, each byte is followed by an acknowledge bit from the I2C module.
Figure 12-7 shows a typical I2C communication format.
