Detailed Description

One pipe's host-visible OUT staging buffer (host -> device payload).

For the DCP (pipe 0) this carries control-write data (e.g. SET_LINE_CODING); for a bulk pipe it carries the host's bulk-OUT bytes. The device drains it through CFIFO and the model reports the remaining count in CFIFOCTR.DTLN.
