37.3.13.5 10-Bit Client Transmission

In 10-bit Client Transmission mode, the state of ABD is ignored. If there is no data in I2CxTXB after the client has received the address high byte with the R/W bit set, hardware sets I2CxTXIF, triggering the DMA to load I2CxTXB. The DMA will continue to load data into I2CxTXB until I2CxCNT reaches a zero value. Once I2CxCNT reaches zero and the data are transmitted from I2CxTXB, I2CxTXIF will not be set, and the DMA will stop loading data.
