DDP-EP31
An endpoint raises a DMA request when Slave mode is disabled by setting the
corresponding bit in the USBEpIntEn register to 0
interrupt occurs (see
- 0x5000
A DMA transfer for an endpoint starts when the endpoint is enabled for DMA operation in
USBEpDMASt, the corresponding bit in USBDMARSt is set, and a valid DD is found for
the endpoint.
All endpoints share a single DMA channel to minimize hardware overhead. If more than
one DMA request is active in USBDMARSt, the endpoint with the lowest physical endpoint
number is processed first.
In DMA mode, the bits corresponding to Interrupt on NAK for Bulk OUT and Interrupt OUT
endpoints (INAK_BO and INAK_IO) should be set to 0 using the SIE Set Mode command
(Section
DMA transfers are described by a data structure called the DMA Descriptor (DD).
DDs are placed in RAM. These descriptors can be located anywhere in on-chip RAM at
word-aligned addresses.
DDs for non-isochronous endpoints are four words long. DDs for isochronous endpoints
are five words long.
The parameters associated with a DMA transfer are:
