constant, independent of speed, to support galvanic isolation for implementations where it is
desirable. The PHY has control over the bidirectional pins. The link only drives these pins when
control is transferred to it by the PHY. The link performs all unsolicited activity through a
dedicated request pin. The possible actions that may occur on the interface are categorized as
transmit, receive, status, and request.
7. Internal Register Configuration
There are 16 accessible internal registers in the PHY. The configuration of the Register at
addresses 0h to7h is fixed. The register 8h to Fh are an index register window whose contents
change based upon the Page_Slect and Port_Select field in Register 7h.
