PHY Mode (MODE[2:0])
This field controls the PHY mode of operation. Refer to
definition of each mode.
PHY Address (PHYADD)
The PHY Address field determines the MMI address to which the PHY will
respond and is also used for initialization of the cipher (scrambler) key. Each
PHY must have a unique address. Refer to
Addressing," on page 84
Note:
Port x PHY Special Modes Register (PHY_SPECIAL_MODES_x)
This read/write register is used to control the special modes of the Port x PHY.
Note: This register is re-written by the EEPROM Loader following the release of reset or a RELOAD
Note 13.60 Register bits designated as NASR are reset when the Port x PHY Reset is generated via
Note 13.61 The default value of this field is determined by a combination of the configuration straps

the default MODE[2:0] value is 111b. Else, the default value of this field is determined by
the remaining straps. MODE[2]=0, MODE[1]=(speed_strap_1 for Port 1 PHY,
speed_strap_2 for Port 2 PHY), and MODE[0]=(duplex_strap_1 for Port 1 PHY,
duplex_strap_2 for Port 2 PHY). Configuration strap values are latched upon the de-
