In 7-bit Slave Transmission mode, the state of
ABD is ignored. If the slave 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.
