PHY Management Interface Access Register (PMI_ACCESS)
This register is used to control the management cycles to the PHYs. A PHY access is initiated when
this register is written. This register is used in conjunction with the
Register (PMI_DATA)
Note: This register is only accessible by the EEPROM Loader and NOT by the Host bus. Refer to
This bit must always be written with a value of 1.
