6.10. Transceiver Interface Reconfiguration
For example, you can reconfigure the custom PHY IP to enable or disable the 8B/10B encoder/decoder. There is no limit to the number of functional modes you can reconfigure the transceiver channel to if the various clocks involved support the transition. When you switch the custom PHY IP from one function mode to a different function mode, you may need to reconfigure the FPGA fabric-transceiver channel data width, enable or disable PCS sub-blocks, or both, to comply with the protocol requirements.
Channel reconfiguration only affects the channel involved in the reconfiguration (the transceiver channel specified by the unique logical channel address), without affecting the remaining transceiver channels controlled by the same Transceiver Reconfiguration Controller. PLL reconfiguration affects all channels that are currently using that PLL for transmission.
Channel reconfiguration from either a transmitter-only configuration to a receiver-only configuration or vice versa is not allowed.
