Texas Instruments TM4C1294NCPDT User Manual

4. Once the Ethernet PHY Peripheral Ready (PREPHY) register reads 0x0000.0001, software
can write the EMACPC register with the required value.
5. After software configuration is complete, the application must set the DONE bit in the Ethernet
PHY Configuration 1 (EPHYCFG1) register at offset 0x009.
Note: If a software reset is asserted to the PHY afterwards through the SREPHY register, the
custom configuration is lost and the steps described above must be repeated.
20.6 Register Map
Table 20-23 on page 1467 lists the Ethernet Controller MAC and PHY registers. For the MAC registers,
the offset listed is a hexadecimal increment to the MAC base address of 0x400E.C000. PHY registers
are accessed through the EMACMIIADDR register thus the base address is n/a (not applicable)
and noted as such above the register descriptions.
The IEEE 802.3 standard specifies a register set for controlling and gathering status from the PHY
layer. The registers are collectively known as the MII Management registers. Table 20-23 on page 1467
also lists these MII Management registers for interfacing to the internal PHY. All addresses given
are absolute and are written directly to the MII field of the Ethernet MAC MII Address
(EMACMIIADDR) register, offset 0x010. The PLA value of the EMACMIIADDR register for the
internal PHY is 0x00.
