(b) EP2 DMA Transfer Procedure
The DMAC transfer unit should be one packet. Therefore, set the number of transfers so that it is
equal to or less than the maximum packet size of each endpoint.
1. Wait for the UIFR1/EP2READY flag to be set.
2. DMAC settings for EP2 data transfer (such as auto-request and address setting). Read value of
3. Activate the DMAC (write 1 to DTE after reading DTE as 0).
4. DMA transfer (transfer of 64 bytes or less).
5. Write 1 to the UTRG0/EP2RDFN bit after the DMA transfer is completed.
6. Repeat steps 1 to 5 above.
