Hardware Control Interface
The Hardware Control Interface consists of MF<4:0>, CFG <1:0> and FDE input pins. This
interface is used to configure operating characteristics of the LXT970A Transceiver and to
determine the MDIO Address. When MDDIS is Low, the Hardware Control Interface provides
initial values for the MDIO registers, and then passes control to the MDIO Interface.
When MDDIS is High, the Hardware Control Interface provides continuous control over the
LXT970A Transceiver. Individual chip addressing allows multiple LXT970A Transceiver devices
to share the MII in either mode.
