6.6 Functional Block: Management Interface
6.6.1 Management Register Set Summary
6.6.2 Management Frame Structure
ICS1893Y-10 Rev F 1/20/04
As part of the MAC/Repeater Interface, the ICS1893Y-10 provides a two-wire serial management interface
which complies with the ISO/IEC 8802-3 standard MII Serial Management Interface. This interface is used
to exchange control, status, and configuration information between a Station Management entity (STA) and
the physical layer device (PHY). The PHY and STA exchange this data through a pre-defined set of
management registers. The ISO/IEC standard specifies the following components of this serial
management interface:
•
•
•
In compliance with the ISO/IEC specification, the ICS1893Y-10 implementation of the serial management
interface provides a bi-directional data pin (MDIO) along with a clock (MDC) for synchronizing the
exchange of data. These pins remain active in all ICS1893Y-10 MAC/Repeater Interface modes (that is, the
10/100 MII, 100M Symbol, and 10M Serial interface modes).
The ICS1893Y-10 implements a Management Register set that adheres to the ISO/IEC standard. This
register set (discussed in detail in
Control and Status registers and the ISO/IEC ‘Extended’ registers as well as some ICS-specific registers.
The Serial Management Interface is a synchronous, bi-directional, two-wire, serial interface for the
exchange of configuration, control, and status data between a PHY, such as an ICS1893Y-10, and an STA.
All data transferred on an MDIO signal is synchronized by its MDC signal. The PHY and STA exchange
data through a pre-defined register set.
The ICS1893Y-10 complies with the ISO/IEC defined Management Frame Structure and protocol. This
structure supports both read and write operations.
