Table 1–33
Table 1–33. Single Width Functional Modes for the Byte Ordering Block
For more information about configurations that allow the byte ordering block in the
receiver datapath, refer to
The Quartus II software automatically configures the byte ordering pattern and byte
ordering PAD pattern for SONET/SDH OC-48 functional mode. For more
information, refer to
In Basic single-width mode, you can program a custom byte ordering pattern and
byte ordering PAD pattern in the ALTGX MegaWizard Plug-In Manager.
lists the byte ordering pattern length allowed in Basic single-width mode.

pattern must be 1'b0. The least significant 8 bits must be the 8B/10B decoded version of the code group used for
byte ordering.
