Bit Reversal and Polarity Inversion
The bit reversal and polarity inversion functions allow you to reverse bit order, byte order, and polarity to
correct errors and to accommodate different layouts of data.
Table 15-15: Bit Reversal and Polarity Inversion Parameters
Parameter Range Description
Enable TX bit reversal On/Off When you turn this option On, the
word aligner reverses TX parallel data
before transmitting it to the PMA for
serialization. You can only change this
static setting using the Transceiver
Reconfiguration Controller.
Enable RX bit reversal On/Off When you turn this option On, the rx_
std_bitrev_ena port controls bit
reversal of the RX parallel data after it
passes from the PMA to the PCS.
Enable RX byte reversal On/Off When you turn this option On, the
word aligner reverses the byte order
before transmitting data. This function
allows you to reverse the order of bytes
that were erroneously swapped. The
PCS can swap the ordering of both 8
and10 bit words.
