23.15:12, 2:1– MAC/Media Interface Mode Select
Bits 23.15:12 and 23.2:1 are used to select the MAC interface modes and media interface modes. The reset value for these bits
is dependent upon the state of the MAC Interface bits in the CMODE hardware configuration. All combinations of these bits not
indicated below are reserved:

23.11:10 – RGMII/RTBI TXC Skew Selection
Bits 23.11:10 specify the amount of clock delay added to the TX_CLK line inside the VSC8211 when using an RGMII or RTBI
interface. By enabling this internal delay, a PCB “trombone” delay is not required as specified by the RGMII standard. Multiple
values are provided to compensate for PCB trace skews. The default values of these bits are specified by the RGMII Skew bits
in the CMODE hardware configuration. See Table 27,
information.
23.9:8 – RGMII/RTBI RXC Skew Selection
Bits 23.9:8 specify the amount of clock delay added to the RX_CLK line inside the VSC8211 when using an RGMII or RTBI
interface. By enabling this internal delay, a PCB “trombone” delay is not required as specified by the RGMII standard. Multiple

PHY Operat-
ing Modes
In this mode, the PHY does not drop the Fiber Media link if the CAT5 link comes up after the Fiber Link has been established. It is therefore not a suitable mode for
unmanaged applications. For more information on how to use this mode in managed applications, contact your Vitesse representative.
PHY registers are not supported in this mode.
In this mode, the PHY’s MAC and media interfaces are the same. Both interfaces can be either SGMII or 802.3z SerDes.
