DBOEN: Double-buffer Enable
0: Double-buffering disabled for the selected OUT endpoint.
1: Double-buffering enabled for the selected OUT endpoint.
ISO: Isochronous Transfer Enable
This bit enables/disables isochronous transfers on the current endpoint.
0: Endpoint configured for bulk/interrupt transfers.
1: Endpoint configured for isochronous transfers.
EOCL holds the lower 8-bits of the 10-bit number of data bytes in the last received packet in
the current OUT endpoint FIFO. This number is only valid while OPRDY = ‘1’.
EOCH holds the upper 2-bits of the 10-bit number of data bytes in the last received packet in
the current OUT endpoint FIFO. This number is only valid while OPRDY = ‘1’.
