14.3.2
UDMAR is set when data transfer by means of a USB request of the on-chip DMAC is performed
for data registers UEDR1 and UEDR2 corresponding to EP1 and EP2 respectively used for Bulk
transfer. For the DMAC transfer, set DREQ0 and DREQ1 separately. If DREQ0 and DREQ1
usage overlaps, the USB cannot operate correctly. For details on DMAC transfer, refer to section
14.6, DMA Transfer Specifications.
Note: As the DREQ signal is not used in the data transfer by auto request of the on-chip DMAC,
