Table 357. DMA descriptor
[1]
Legend: R - Read; W - Write; I - Initialize
Pointer to the memory location from where the next DMA descriptor will be fetched.
Specifies the DMA mode of operation. Two modes have been defined: Normal and
Automatic Transfer Length Extraction (ATLE) mode. In normal mode, software initializes
the DMA_buffer_length for OUT endpoints. In ATLE mode, the DMA_buffer_length is
extracted from the incoming data. See
(ATLE) mode operation” on page 383
This bit indicates whether the software has prepared the next DMA descriptor. If set, the
DMA engine fetches the new descriptor when it is finished with the current one.
When set, this bit indicates that the descriptor belongs to an isochronous endpoint. Hence
5 words have to be read when fetching it.
The maximum packet size of the endpoint. This parameter is used while transferring the
data for IN endpoints from the memory. It is used for OUT endpoints to detect the short
packet. This is applicable to non-isochronous endpoints only. This field should be set to
the same MPS value that is assigned for the endpoint using the USBMaxPSize register.
