Management Interface
This chapter describes the Management Interface, over which the internal device
registers are accessed. It contains the following sections:
• Section 4.1, “Signal Description”
• Section 4.2, “General Operation”
• Section 4.3, “Multiple Register Access”
• Section 4.4, “Frame Structure”
• Section 4.5, “Register Structure”
• Section 4.6, “Interrupts”
The Management Interface, referred to as the MI serial port, is an eight-pin
bidirectional link through which the internal device registers are accessed. The
internal register bits control the configuration and capabilities of the device, and
reflect device status.
The MI serial port provides access to 11 internal registers and meets all IEEE 802.3
specifications for the Management Interface.
