integrates a complete 100Base-TX module and a complete
10Base-T module. The DM9161A provides a Media
Independent Interface (MII) as defined in the IEEE 802.3u
standard (Clause 22).
The DM9161A performs all PCS (Physical Coding Sublayer),
PMA (Physical Media Access), TP-PMD (Twisted Pair

7.1 MII Interface
The DM 9161A provides a Media Independent Interface (MII)
as defined in the IEEE 802.3u standard (Clause 22).
The purpose of the MII interface is to provide a simple, easy
to implement connection between the MAC Reconciliation
layer and the PHY. The MII is designed to make the
differences between various media transparent to the MAC
sublayer.
The MII consists of a nibble wide receive data bus, a nibble
wide transmit data bus, and control signals to facilitate data
transfers between the PHY and the Reconciliation layer.
TXD (transmit data) is a nibble (4 bits) of data that are
driven by the reconciliation sublayer synchronously with
respect to TXCLK. For each TXCLK period, which
TXEN is asserted, TXD (3:0) are accepted for
transmission by the PHY.
TXCLK (transmit clock) output to the MAC reconciliation
sublayer is a continuous clock that provides the timing
reference for the transfer of the TXEN, TXD, and TXER
signals.
TXEN (transmit enable) input from the MAC
reconciliation sublayer indicates that nibbles are being
presented on the MII for transmission on the physical
medium.
