20.5.7 DMA Operation
The DMA can be used to transfer the data without the participation of the CPU. The I2CxTXIF and I2CxRXIF interrupts can be used to trigger DMA.
Note:
- Packet size (PSZ) should be configured before data transmit/receive.
- ND/A should be configured accordingly to indicate address/data transmission.
- It is recommended to use Smart mode when using DMA to reduce CPU interaction.
