Figure 2–15. Word Aligner in Bit-Slip Mode
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
Manager.
The bit-slip mode is available only in Custom mode and SONET mode.
