Endpoint 1 DMA Transfer Enable
Description
When this bit is set, a DMAC start interrupt signal
(USBINTN0) is asserted and DMA transfer is enabled
from the endpoint 1 receive FIFO buffer to memory. If
there is at least one byte of receive data in the FIFO
buffer, the DMAC start interrupt signal (USBINTN0) is
asserted. In DMA transfer, when all the received data
is read, EP1 is automatically read and the completion
trigger operates.
EP1-related interrupt requests to the CPU are not
automatically masked.
•
1. Write of 1 to the EP1 DMAE bit in DMA
2. Set the DMAC to activate through USBINTN0
3. Transfer count setting in the DMAC
4. DMAC activation
5. DMA transfer
6. DMA transfer end interrupt generated
See section 15.8.2, DMA Transfer for Endpoint 1.
