33.6.4.1.1 Client DMA

When using the I²C client with DMA, an address match will cause the address Interrupt flag (INTFLAG.ADDRMATCH) to be raised. After the interrupt has been serviced, data transfer will be performed through DMA.

The I²C client generates the following requests:

Write data received (RX): The request is set when host write data is received. The request is cleared when DATA is read.
Read data needed for transmit (TX): The request is set when data is needed for a host read operation. The request is cleared when DATA is written.
