Data OUT 1
For OUT transfer, the bank will be automatically cleared by hardware when the application has
read all the bytes in the bank (the bank is empty).
Note: When a zero-length-packet is received, RX_BK_RDY bit in UDPHS_EPTSTAx is cleared
automatically by AUTO_VALID, and the application knows of the end of buffer by the presence
of the END_TR_IT.
Note: If the host sends a zero-length packet, and the endpoint is free, then the device sends an
ACK. No data is written in the endpoint, the RX_BY_RDY interrupt is generated, and the
BYTE_COUNT field in UDPHS_EPTSTAx is null.
