Regular ContributorHi,
Regarding your inquiry on the gray coding control, yes. For FGT, Gray coding is forced On in the PAM4 GUI but is explicitly disableable through register writes. Use read-modify-write access:
TX: 0x47808[3] = 0
RX: 0x47810[2] = 0
You may refer to the F-Tile PMA and FEC Direct PHY IP Register Map for further details (https://docs.altera.com/v/u/resources/647401/f-tile-pma-and-fec-direct-phy-ip-register-map). Thank you.
