The procedure of the DMA transfer in case of serial data transmission is shown in Figure 6-17.
Figure 6-17:
Initialization of DMA Transfer for Serial Data Transmission
Remark:
n = 0, 1
(number of serial interface channel)
x = 6, 7
(number of DMA channel)
Initialization of DMA transfer for
serial data transmission
(DMA channel 6 or 7)
Set up MARx register with the source start
address in iRAM
Specify the DMA transfer count in the
DTCRx register (1 to 256)
Clear status bit of DMA channel x:
DMASx bit = 0
Enable DMA transfer channel x:
DEx bit = 1
End of initialization
Specify the DMA trigger factor in the
DTFRx register depending on the used
serial interface (CSI3n, CSIBn, UARTCn)
Select the DMA transfer data size (8 or 16
bits) by the DMADSCx bit in the DMADSC
register
