functional mode, and allowed alignment pattern length for Arria II devices.
Receiver bit reversal—This feature is only available in Basic mode. By default, the
Arria II GX and GZ receiver assumes LSB-to-MSB transmission. If the transmission
order is MSB-to-LSB, the receiver forwards the bit-flipped version of the parallel
data to the FPGA fabric on the rx_dataout port. The receiver bit reversal feature is
available to correct this situation by flipping the parallel data so that the
rx_dataout port contains the correct bit-ordered data.
This feature is available through the rx_revbitordwa port in Basic mode only with
the word aligner configured in bit-slip mode. When you drive the rx_revbitordwa
signal high in this configuration, the 8-bit or 10-bit data D[7:0] or D[9:0] at the
output of the word aligner gets rewired to D[0:7] or D[0:9], respectively.
