Cells are transferred from a 53/53/54(54/54/56) byte bus
to a 53/54/54(54/56/56) byte bus.

The content of H5 is output at the far-end, UDF is
stripped/undefined if present. There is no cell prepend
other than the PHY address if Any-PHY is used.

Cells are transferred from the CSD receive port and a
53/54/54(54/56/56) byte bus.
The content of H5 is output at the far-end, UDF is
undefined if present.
Cells are transferred from a 53/53/54(54/54/56) byte bus
to the CSD transmit port.
If DHCS=1, H5 is passed transparently. If DHCS=0, it is
replaced by the calculated HCS value.
THIS CONFIGURATION IS VALID ONLY IF OMASTER=0
AND OANYPHY=0 AT THE FAR END DEVICE.
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).
THIS CONFIGURATION IS VALID ONLY IF OMASTER=0
AND OANYPHY=0 AT THE FAR END DEVICE.
Cells are transferred from a 53/53/54(54/54/56) byte bus
