Configuration examples of UDPHS_EPTCTLx (UDPHS Endpoint Control Register) for Bulk IN
endpoint type follow below.
• With DMA
– AUTO_VALID: Automatically validate the packet and switch to the next bank.
– EPT_ENABL: Enable endpoint.
• Without DMA:
– TX_BK_RDY: An interrupt is generated after each transmission.
– EPT_ENABL: Enable endpoint.
Configuration examples of Bulk OUT endpoint type follow below.
• With DMA
– AUTO_VALID: Automatically validate the packet and switch to the next bank.
– EPT_ENABL: Enable endpoint.
• Without DMA
– RX_BK_RDY: An interrupt is sent after a new packet has been stored in the endpoint
FIFO.
– EPT_ENABL: Enable endpoint.
