Chapter 7 Ethernet PHYs
Revision 1.4 (07-07-10)
7.1
7.1.1
phy_addr_sel_strap
The device contains three PHYs: Port 1 PHY, Port 2 PHY and a Virtual PHY. The Port 1 & 2 PHYs
are identical in functionality and each connect their corresponding Ethernet signal pins to the Switch
Fabric MAC of their respective port. These PHYs interface with their respective MAC via an internal
MII interface. The Virtual PHY provides the virtual functionality of a PHY and allows connection of an
external MAC to Port 0 of the Switch Fabric as if it was connected to a single port PHY. All PHYs
comply with the IEEE 802.3 Physical Layer for Twisted Pair Ethernet and can be configured for full/half
duplex 100 Mbps (100BASE-TX) or 10Mbps (10BASE-T) Ethernet operation. All PHY registers follow
the IEEE 802.3 (clause 22.2.4) specified MII management register set and can be configured indirectly
via the external MII interface signals, or directly via the memory mapped Virtual PHY registers. In
addition, the Port 1 PHY and Port 2 PHY can be configured via the PHY Management Interface (PMI).
Refer to
registers.
The Ethernet PHYs are discussed in detail in the following sections:
PHY Addressing
Each individual PHY is assigned a unique default PHY address via the
configuration strap as shown in
be changed via the
(PHY_SPECIAL_MODES_x). For proper operation, all PHY addresses must be unique. No check is
performed to assure each PHY is set to a different address. Configuration strap values are latched
upon the de-assertion of a chip-level reset as described in
page
