the register returns the number of remaining bytes in the current transfer. A bus reset
will not change the programmed bit values.

Description
A logic 1 enables the generation of an EOT condition, when the
DMA Counter register reaches zero. Bus reset value:
unchanged.
A logic 1 enables short/empty packet mode. When receiving
(OUT endpoint) a short/empty packet an EOT condition is
generated. When transmitting (IN endpoint), this bit should be
cleared. Bus reset value: unchanged.
reserved
This bit is logic 0 when the last DMA access is a byte (LSB byte
valid; MSB byte invalid). This bit is logic 1 when the last DMA
access is a word (LSB byte valid; MSB byte invalid).
Indicates the destination endpoint for DMA, see
Writing a logic 1 enables DMA transfer, a logic 0 forces the end
of an ongoing DMA transfer. Reading this bit indicates whether
DMA is enabled (0 = DMA stopped, 1 = DMA enabled). This bit
is cleared by a bus reset.
reserved
Selects the DMA burst length:
00 — single-cycle mode (1 byte)
01 — burst mode (4 bytes)
10 — burst mode (8 bytes)
11 — burst mode (16 bytes).
Bus reset value: unchanged.
