CLEAR CHANNEL MODE
Cells are transferred from a 53/53/54(54/54/56) byte bus
to the CSD transmit port.
H5 is not transported and must be generated at the

Cells are transferred from a 52/52/53(52/52/54) byte bus
to a XX/53/XX(XX/54/XX) byte bus (SCI-PHY slave
only).
Neither an address field nor a cell prepend exist. The
PHY address is contained in H5 (H5/UDF).
