PHYAD0
I/O
The PHY Address, PHYAD[4:0], is latched at power-up / reset and is configurable to
any value from 1 to 31. Each PHY address bit is configured as follows:
Pull-up = 1
Pull-down = 0

CLK125_EN
I/O
CLK125_EN is latched at power-up / reset and is defined as follows:
Pull-up = Enable 125MHz Clock Output
Pull-down = Disable 125MHz Clock Output
Pin 107 (CLK125_NDO) provides the 125MHz reference clock output option for use
by the MAC.
Notes:
1. I/O = Bi-directional.
2. Pin strap-ins are latched during power-up or reset. In some systems, the MAC receive input pins may be driven during power-up or reset,
and consequently cause the PHY strap-in pins on the GMII/MII signals to be latched to the incorrect configuration. In this case, it is
recommended to add external pull-ups/pull-downs on the PHY strap-in pins to ensure the PHY is configured to the correct pin strap-in mode.
