MII Management Interface (MIIM)
A standard MIIM interface is provided for all five PHY devices in the KS8995MA/FQ. An external device with
MDC/MDIO capability is able to read PHY status or to configure PHY settings. The device is able to meet IEEE
specification of 2.5MHz MDC clock. For details on the MIIM interface standard please reference the IEEE 802.3
specification (section 22.2.4.5). The MIIM interface does not have access to all the configuration registers in the
KS8995MA/FQ. It can only access the standard MII registers. See “MIIM Registers.” The SPI interface, on the other
hand, can be used to access the entire KS8995MA/FQ feature set.
