The registers below can be accessed only in Clause 45 mode and with device address field set to 0x01
(DA[4:0] = 5’b00001).
NOTE: Link training registers can also be accessed in Clause 22 mode using indirect address method and
in Clause 45 mode with device address field set to 0x1E (DA[4:0] = 5’b11110). Link training registers are
also applicable in 10G and 1GKX modes.
