NAME
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
"Configuration Straps," on page 45
full-duplex flow control must be controlled manually by the host, based upon the external
PHYs Auto-negotiation results.
