In the bit-slip mode, the byte boundary can be modified by a barrel shifter
to slip the byte boundary one bit at a time via a user-controlled bit-slip
port. The bit-slip mode supports both 8-bit and 10-bit data paths
operating in a single or double-width mode.
The pattern detector is active in the bit-slip mode, and it detects the
user-defined pattern that is specified in the MegaWizard® Plug-In
Manager.
The bit-slip mode is available only in Custom mode and SONET mode.
Figure 2–16 shows the word aligner in 16-bit mode.
