There are 11 registers with 16 bits each supported for the STE100P. These include 7 basic registers which
are defined according to the clause 22 “Reconciliation Sublayer and Media Independent Interface” and
clause 28 “Physical Layer link signaling for 10 Mb/s and 100 Mb/s Auto-Negotiation on twisted pair” of
IEEE802.3u standard.
In addition, there are 4 special registers for advanced chip control and status information.
