The MII connects Media Access Control (MAC) … See more MII has two signal interfaces: • A Data interface to the Ethernet MAC, for sending and receiving Ethernet frame data. • A PHY management interface, MDIO, used to read and write the control and status registers … See more The MDIO interface is implemented by two signals: • MDIO Interface Clock (MDC): clock driven by the MAC device … See more PRE_32 The first field in the MDIO header is the Preamble. During the preamble, the MAC sends 32 bits, all '1', on the MDIO line. ST The Start field consists of 2 bits and always contains the … See more • Clause 22 Access to Clause 45 Registers See more Before a register access, PHY devices generally require a preamble of 32 ones to be sent by the MAC on the MDIO line. The access consists of 16 control bits, followed by 16 data bits. The control bits consist of 2 start bits, 2 access type bits (read or write), the PHY … See more IEEE 802.3 Part 3 use different opcodes and start sequences. Opcodes 00(set address) and 11(read)/01(write)/10(read increment) are used as two serial transactions to read and write registers. See more bridgend function rooms
