Figure 1–56. Receiver Bit Reversal in Double-Width Mode
Because receiver bit reversal is done at the output of the word aligner, a dynamic bit
reversal also requires a reversal of the word alignment pattern. As a result, the
Receiver Bit Reversal feature is dynamic only if the receiver is dynamically
reconfigurable (it allows changing the word alignment pattern dynamically) or uses
manual bit slip alignment mode (no word alignment pattern). The Receiver Bit
Reversal feature is static in all other Basic mode configurations. You can enable this
feature using the MegaWizard Plug-In Manager. In configurations where the Receiver
Bit Reversal feature is dynamic, an rx_revbitordwa port is available to control the bit
reversal dynamically. A high on the rx_revbitordwa port reverses the bit order at the
input of the word aligner.
