2.9.2.5. RX Bit Reversal
The RX bit reversal feature can be enabled in low latency, basic, and basic rate match
mode. The word aligner is available in any mode, bit slip, manual, or synchronous
state machine.
To enable this feature, select the Enable RX bit reversal and Enable
rx_std_bitrev_ena port options. This adds
than one channel in the design,
bit corresponds to a channel. As long as
data received by the core shows bit reversal.
You can verify this feature by monitoring

2.9.2.6. RX Byte Reversal
The RX byte reversal feature can be enabled in low latency, basic, and basic rate
match mode. The word aligner is available in any mode.
To enable this feature, select the Enable RX byte reversal and Enable
rx_std_byterev_ena port options. This adds
more than one channel in the design,
each bit corresponds to a channel. As long as
RX data received by the core shows byte reversal.
You can verify this feature by monitoring
