Bits 11 - 15: PHY Address (PHYA[0:4]) These 5 bits select one of the 32 available PHY address locations to
access through the PHY management (MDIO) bus.
Bits 6 - 10: MII Address (MIIA[0:4]) - These 5 bits are the address location within the PHY that is being
accessed.
Bit 1: MII Write (MIIW) Write this bit to 1 in order to execute a write instruction over the MDIO interface. Write the
bit to zero to execute a read instruction.
Bit 0: MII Busy (MIIB) This bit is set to 1 by the DS33Z11 during execution of a MII management instruction
through the MDIO interface, and is set to zero when the DS33Z11 has completed the instruction. The user should
read this bit and ensure that it is equal to zero prior to beginning a MDIO instruction.
