Set the transfer count in both ETCRH and ETCRL.
Read DTCR while the DTE bit is cleared to 0.
Set the DTCR bits as follows.
Select the DMAC activation source with bits
DTS2 to DTS0.
Clear the DTIE bit to 0 and set the RPE bit to 1
to select repeat mode.
Select MAR increment or decrement with the
DTID bit.
Select byte size or word size with the DTSZ bit.
Set the DTE bit to 1 to enable the transfer.
