• EPT_ENABL: Endpoint Enable
0 = no effect.
1 = enable endpoint according to the device configuration.
• AUTO_VALID: Packet Auto-Valid Enable
0 = no effect.
1 = enable this bit to automatically validate the current packet and switch to the next bank for both IN and OUT transfers.
• INTDIS_DMA: Interrupts Disable DMA
0 = no effect.
1 = If set, when an enabled endpoint-originated interrupt is triggered, the DMA request is disabled.
• NYET_DIS: NYET Disable (Only for High Speed Bulk OUT endpoints)
0 = no effect.
1 = forces an ACK response to the next High Speed Bulk OUT transfer instead of a NYET response.
• DATAX_RX: DATAx Interrupt Enable (Only for high bandwidth Isochronous OUT endpoints)
0 = no effect.
1 = enable DATAx Interrupt.
• MDATA_RX: MDATA Interrupt Enable (Only for high bandwidth Isochronous OUT endpoints)
0 = no effect.
1 = enable MDATA Interrupt.
• ERR_OVFLW: Overflow Error Interrupt Enable
0 = no effect.
