22.5.7.1 Client Mode Transmission with DMA

Once the client is addressed by the host, ND/A (I2CxCON2[18]) should be set and then the first data should be loaded by the software. Client hardware automatically clears SCLREL and generates the transmit interrupt (I2CxTXIF) after the ACK if the error transmission (I2CEF(I2CxSTAT2[11]) is not set and has not reached the packet size = 0. The transmit buffer status bit TBF(I2CxSTAT1[0]) is clear when the I2CxTRN does not contain any transmit data. At this point, the transmit interrupt (I2CxTXIF) can trigger the DMA to load another byte into the buffer, and the transmit buffer full (TBF) is set. Client hardware sets SCLREL based on data setup time:
