37.3.13 DMA Integration

The I²C module can be used with the DMA for data transfers. The DMA can be triggered through software via the DMA Transaction (DGO) bit or through the use of the following hardware triggers:

• I²C Transmit Interrupt Flag (I2CxTXIF)
• I²C Receive Interrupt Flag (I2CxRXIF)
• I²C Interrupt Flag (I2CxIF)
• I²C Error Interrupt Flag (I2CxEIF)

For I²C communication, the I2CxTXIF is commonly used as the hardware trigger source for host or client transmission, and I2CxRXIF is commonly used as the hardware trigger source for host or client reception.
