Note 3.9

Configuration strap values are latched on power-on reset or nRST de-assertion.

Configuration strap pins are identified by an underlined symbol name. Some configuration

straps can be overridden by values from the EEPROM Loader. Refer to Section 4.2.4,

"Configuration Straps," on page 45 for more information.

Note 3.10 In MAC mode, this strap is not used. In this mode, the Virtual PHY is not applicable, and

full-duplex flow control must be controlled manually by the host, based upon the external

PHYs Auto-negotiation results.

Note 3.11

The IS buffer type is valid only during the time specified in Section 14.5.2, "Reset and

Configuration Strap Timing," on page 390.

Note 3.12 Configuration strap values are latched on power-on reset or nRST de-assertion.

Configuration strap pins are identified by an underlined symbol name. Refer to Section

4.2.4, "Configuration Straps," on page 45 for more information.
