transfer, the CSI transfer must be completed.
INTDMA0
During CSI transfers, no CSI interrupt is generated when the transmitted data of the first byte is written. Therefore,
The received data is automatically transferred from the first byte. (In successive transmission/reception, the data
A DMA interrupt (INTDMA1) occurs when the last transmit data has been writing to the data register. A DMA
Note The DSTn flag is automatically cleared to 0 when a DMA transfer is completed.
Writing the DENn flag is enabled only when DSTn = 0. To terminate a DMA transfer without waiting for
occurrence of the interrupt of DMAn (INTDMAn), set DSTn to 0 and then DENn to 0 (for details, refer to
