1 = DMA transfer enable.
0 = DMA transfer disable
Set to 0
1 = ECP is set as DMA device
1 = indicate the length counter reaches 0, and theTC asserted
0 = DMA memory to memory transfer is disable
1 = DMA transfer between memory and IO is demand mode
0 = DMA transfer between memory and IO is block mode
