It is not in the scope of this document to fully describe the 1000BASE-X PCS registers. See clauses 22 and 37 of the IEEE 802.3-2008 specification for further information.

Registers at undefined addresses are read-only and return 0s. The core can be reset three ways: reset, DCM_LOCKED and soft reset. All of these methods reset all the registers to the default values. For 2500BASE-X the register definition is same as 1000BASE-X.
