This allows the front end to override the default DCR (byte-wide DMA, x86 byte order, 8-byte FIFO) with different transfer size, byte order, DMA parameters, and FIFO threshhold. If the loopback select bit is not set for normal operation, the default is used instead. Inspired by thoughts from Bernd Ernesti.
