More information on the 1000BASE-X PCS registers can be found in clause 22 and clause 37 of the IEEE 802.3-2008 specification. 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.

Note: In the following register definitions, R/W is Read/Write, RO is Read Only.
