Writing one to a bit in this register will clear the corresponding bit in the USBDMARSt
register. Writing zero has no effect.
This register is intended for initialization prior to enabling the DMA for an endpoint. When
the DMA is enabled for an endpoint, hardware clears the corresponding bit in
USBDMARSt on completion of a packet transfer. Therefore, software should not clear the
bit using this register while the endpoint is enabled for DMA operation.
USBDMARClr is a write only register.
The USBDMARClr bit allocation is identical to the USBDMARSt register
Writing one to a bit in this register sets the corresponding bit in the USBDMARSt register.
Writing zero has no effect.
This register allows software to raise a DMA request. This can be useful when switching
from Slave to DMA mode of operation for an endpoint: if a packet to be processed in DMA
mode arrives before the corresponding bit of USBEpIntEn is cleared, the DMA request is
not raised by hardware. Software can then use this register to manually start the DMA
transfer.
