Section 18 Ethernet Controller (EtherC)
MII Register Access Procedure: The program accesses MII registers via the PHY interface
register (PIR). Access is implemented by a combination of 1-bit-unit data write, 1-bit-unit data
read, bus release, and independent bus release. Figure 18.9 shows the MII register access timing.
The timing will differ depending on the PHY-LSI type.
