DMCRC is used to control DMA transfer.
ECLR Bit (DMA Transfer Enable Clear)
The ECLR bit controls behavior of the DEN bit in DMCRE of the given DMACm at the end of DMA transfer.
When the value of the ECLR bit is 1, the DEN bit is cleared to 0 at the end of DMA transfer, disabling subsequent DMA
transfer on the given channel.
When reloading is not in use, set this bit to 1 so that the DEN bit is cleared to 0 at the end of DMA transfer.
Do not set the ECLR bit during data transfer.
