Management Data Disable.
When MDDIS is High, the MDIO is disabled from read and write
operations.
When MDDIS is Low at power-up or reset, the Hardware Control
Interface pins control only the initial or “default” values of their
respective register bits.
After the power-up/reset cycle is complete, bit control reverts to the
MDIO serial channel.
