Receive status entries are written to the status queue following one of three possible events,
end of header, end of buffer, or end of frame. The status event is always written after the
appropriate data transfer has been made. For example the end of frame status is written after
the last byte of data has been written to the data buffer, not before. The EOF and EOB bits in
the status entry can be used to determine the cause of a status entry.
