Functional Block: Management Interface
As part of the MAC/Repeater Interface, the ICS1893AF 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:
A set of registers (Section 7.6.1, “Management Register Set Summary”)
The frame structure (Section 7.6.2, “Management Frame Structure”)
The protocol
In compliance with the ISO/IEC specification, the ICS1893AF 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 ICS1893AF MAC/Repeater Interface modes (that is, the
10/100 MII, 100M Symbol, and 10M Serial interface modes).
7.6.1
Management Register Set Summary
The ICS1893AF implements a Management Register set that adheres to the ISO/IEC standard. This
register set (discussed in detail in Chapter 8, “Management Register Set”) includes the mandatory ‘Basic’
Control and Status registers and the ISO/IEC ‘Extended’ registers as well as some ICS-specific registers.
7.6.2
Management Frame Structure
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 ICS1893AF, 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 ICS1893AF complies with the ISO/IEC defined Management Frame Structure and protocol. This
structure supports both read and write operations. Table 7-2 summarizes the Management Frame
Structure.
Note:
The Management Frame Structure starts from and returns to an IDLE condition. However, the IDLE
periods are not part of the Management Frame Structure.
