Function EMACPHYExtendedWrite

bsp/tm4c129x/libraries/driverlib/emac.c:3001–3022

Writes a value to an extended PHY register. \param ui32Base is the base address of the controller. \param ui8PhyAddr is the physical address of the PHY to access. \param ui16RegAddr is the address of the PHY extended register to be accessed. \param ui16Value is the value to write to the register. When using the internal PHY or when connected to an external PHY supporting extended registers, this
