7-Bit Client Transmission

In 7-bit Client Transmission mode, the state of ABD is ignored. If the client receives the matching 7-bit address and TXBE is set, I2CxTXIF is set by hardware, triggering the DMA to load data into I2CxTXB. Once the data is transmitted from I2CxTXB, I2CxTXIF is set by hardware, triggering the DMA to once again load I2CxTXB with data. The DMA will continue to load data into I2CxTXB until I2CxCNT reaches a zero value. Once I2CxCNT reaches zero and the data is transmitted from I2CxTXB, I2CxTXIF will not be set, and the DMA will stop loading data.
