ICS1889
Media Independent Interface (MII)
The
ICS1889
implements a fully compliant IEEE 802.3μ
Media Independent Interface for connection to MACs or
repeaters which allows connections between the
ICS1889
and MAC on the same board, motherboard/daughter board or
via a cable in a similar manner to AUI connections.
The MII is a specification of signals and protocols which
formalizes the interfacing of a 10/100 Mbps Ethernet Media
Access Controller (MAC) to the underlying physical layer.
The specification is such that different physical media may be
supported (such as 100Base-TX, 100Base-T4 and 100Base-
FX) transparently to the MAC.
The MII specifies transmit and receive data paths. Each path
is 4-bits wide allowing for transmission of a nibble or single
symbol. The transmit data path includes a transmit clock for
synchronous transfer, a transmit enable signal and a transmit
error signal. The receive data path includes a receive data
clock for synchronous transfer, a receive data valid signal and
a receive error signal. Both the transmit clock and receive
clock are sourced by the
ICS1889
. The
ICS1889
provides the
MII signals carrier sense and collision detect. In half duplex
mode, carrier sense indicates that data is being transmitted or
received, and in full duplex mode it indicates that data is
being received. Collision detect indicates that data has been
received while a transmission is in progress.
The MII also specifies a two wire interface and a protocol
between station management and the physical layer. The
ICS1889
implements this interface providing a bidirectional
data line and a clock input for synchronizing the data
transfers. This interface allows station management to read
and write all of the
ICS1889
registers.
The
ICS1889
is designed to allow hot insertion of an MII
cable into the MAC. During the power-up phase, the
ICS1889
will isolate the MII and the transmit pair by
tristating the PHY outputs.
