the DcDMACounter register. When the internal counter completes the transfer as
programmed in the DcDMACounter, an EOT condition is generated and the DMA
operation stops.
Short packet:
Normally, the transfer byte count must be set via a control endpoint
before any DMA transfer takes place. When a short packet has been enabled as EOT
indicator (SHORTP = 1), the transfer size is determined by the presence of a short
packet in the data. This mechanism permits the use of a fully autonomous data
transfer protocol.
When reading from an OUT endpoint, reception of a short packet at an OUT token
will stop the DMA operation after transferring the data bytes of this packet.
[1]
The DMA transfer stops. However, no interrupt is generated.
12.4.2
Isochronous endpoints
A DMA transfer to/from an isochronous endpoint can be terminated by any of the
following conditions (bit names refer to the DcDMAConfiguration register, see
Table 86
):
An external End-Of-Transfer signal occurs on input EOT
The DMA transfer completes as programmed in the DcDMACounter register
(CNTREN = 1)
An End-Of-Packet (EOP) signal is detected
DMA operation is disabled by clearing bit DMAEN.
