Table 36. Bit Reversal and Polarity Inversion
Parameter Range Description
Enable TX bit reversal On / Off When you turn on this option, the 8B/10B Encoder reverses TX
parallel data before transmitting it to the PMA for serialization.
The transmitted TX data bit order is reversed. The normal order
is LSB to MSB. The reverse order is MSB to LSB. During the
operation of the circuit, this setting can be changed through
dynamic reconfiguration.
Enable TX byte reversal On / Off When you turn on this option, the 8B/10B Encoder 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 either one of the 8- or 10-bit
words, when the PCS/PMA interface width is 16 or 20 bits. This
option is not valid under certain Transceiver configuration
rules.
Enable TX polarity
inversion
On / Off
When you turn on this option, the tx_std_polinv port controls
polarity inversion of TX parallel data to the PMA. When you turn
on this parameter, you also need to turn on the Enable
tx_polinv port.
Enable tx_polinv port On / Off
When you turn on this option, the tx_polinv input control port
is enabled. You can use this control port to swap the positive and
negative signals of a serial differential link, if they were
erroneously swapped during board layout.
Enable RX bit reversal On / Off When you turn on this option, the word aligner reverses RX
parallel data. The received RX data bit order is reversed. The
normal order is LSB to MSB. The reverse order is MSB to LSB.
This setting can be changed through dynamic reconfiguration.
When you enable Enable RX bit reversal, you must also enable
Enable rx_std_bitrev_ena port.
Enable rx_std_bitrev_ena
port
On / Off When you turn on this option and assert the
rx_std_bitrev_ena control port, the RX data order is
reversed. The normal order is LSB to MSB. The reverse order is
MSB to LSB.
Enable RX byte reversal On / Off When you turn on this option, the word aligner reverses the byte
order, before storing the data in the RX FIFO. This function allows
you to reverse the order of bytes that are erroneously swapped.
The PCS can swap the ordering of either one of the 8- or 10-bit
words, when the PCS / PMA interface width is 16 or 20 bits. This
option is not valid under certain Transceiver configuration
rules.
When you enable Enable RX byte reversal, you must also
select the Enable rx_std_byterev_ena port.
Enable
rx_std_byterev_ena port
On / Off When you turn on this option and assert the
rx_std_byterev_ena input control port, the order of the
individual 8- or 10-bit words received from the PMA is swapped.
Enable RX polarity
inversion
On / Off
When you turn on this option, the rx_std_polinv port inverts
the polarity of RX parallel data. When you turn on this
parameter, you also need to enable Enable rx_polinv port.
Enable rx_polinv port On / Off
When you turn on this option, the rx_polinv input is enabled.
You can use this control port to swap the positive and negative
signals of a serial differential link if they were erroneously
swapped during board layout.
Enable rx_std_signaldetect
port
On / Off When you turn on this option, the optional
rx_std_signaldetect output port is enabled. This signal is
required for the PCI Express protocol. If enabled, the signal
threshold detection circuitry senses whether the signal level
present at the RX input buffer is above the signal detect
