DMA is enabled (DMAEN = 1), the internal DMA counter is loaded with the value from
the DMA Counter Register. When the internal counter reaches zero an EOT condition
is generated and the DMA operation stops.
Short/empty packet:
Normally, the transfer byte count must be set via a control
endpoint before any DMA transfer takes place. When a short/empty packet has been
enabled as EOT indicator (SHORTP = 1), the transfer size is determined by the
presence of a short/empty 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/empty packet at an OUT
token will stop the DMA operation after transferring the data bytes of this packet.
When writing to an IN endpoint, a short packet transferred at an IN token will stop the
DMA operation after all bytes have been transferred. If the number of bytes in the
buffer is zero, ISP1161 DC will automatically send an empty packet.
[1]
If short/empty packet EOT is enabled (SHORTP = 1 in DMA Configuration Register) and DMA
Counter Register is zero.
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 DMA Configuration Register, see
Table 85
):
An external End-Of-Transfer signal occurs on input EOT
The internal DMA Counter Register reaches zero (CNTREN = 1)
An End-Of-Packet (EOP) signal is detected
DMA operation is disabled by clearing bit DMAEN.
