Table 87:
For selecting an endpoint for device DMA transfer, see
This command accesses the DcDMACounter register. The bit allocation is given in
Table
the register returns the number of remaining bytes in the current transfer. A bus reset
will not change the programmed bit values.
The internal DMA counter is automatically reloaded from the DcDMACounter register
when DMA is re-enabled (DMAEN = 1). See

Description
Logic 1 enables the generation of an EOT condition, when the
DcDMACounter register reaches zero. Bus reset value:
unchanged.
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
Indicates the destination endpoint for DMA, see
Writing logic 1 enables DMA transfer, 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.
