25 PHY Register Set
25.1 Clause 28/37 Resister View
PHY registers 0 through 15 are implemented according to the IEEE 802.3 specification. According to this standard, the contents
of MII Registers 4, 5, 6, 9 and 10 are different for 1000BASE-X PHYs and 1000BASE-T PHYs. Since the VSC8211 supports
both Fiber (1000BASE-X) and CAT5 (1000BASE-T) media, it supports both register sets.
In registers 0 through 15, the 1000BASE-T register set is referred to as the “Clause 28 View” and the 1000BASE-X register set
is referred to as the “Clause 37 View”.
The default register view is “Clause 28 View” for all PHY Operating Modes. To switch the Register View to “Clause 37 View”, set
the “Register View” bit (MII Register 23.4). Refer to
section 19, “Hardware Configuration Using CMODE Pins,”
page 66, and
section 20, “EEPROM Interface,”
page 72 for details on Register View configuration at startup.
• Please note that “Clause 37" Register View is allowed only in 'GMII/RGMII to CAT5/Fiber/AMS' category of PHY
operating modes i.e. where MII Register 23.15:12,23.2:1 = 6'b00xxxx.
