8.14.3 PHY MII Management Block and MDIO Interface
The MII Management Block allows for the host to control up to 32 PHYs, each with 32 registers. The MII block
communicates with the external PHY using 2-wire serial interface composed of MDC (serial clock) and MDIO for
data. The MDIO data is valid on the rising edge of the MDC clock. The Frame format for the MII Management
Interface is shown
Figure 8-8
. The read/write control of the MII Management is accomplished through the indirect
SU.MACMIIA MII Management Address Register and data is passed through the indirect SU.MACMIID Data
Register. These indirect registers are accessed through the MAC Control Registers defined in
Table 8-6
. The
MDC clock is internally generated and runs at 1.67 MHz.
