1 — DMA counter is enabled. Once the counter is
enabled, the HCD must initialize the HcTransferCounter
register to a non-zero value for DREQ to be raised after
the DMAEnable bit is set to HIGH.
00 — single-cycle burst DMA
01 — 4-cycle burst DMA
10 — 8-cycle burst DMA
11 — reserved
I/O bus with 32-bit data path width supports only single
and four cycle DMA burst.
0 — DMA is disabled
1 — DMA is enabled
This bit needs to be reset when the DMA transfer is
completed.
