PHY Pins
The 82574L has built in termination resistors. As a result, external termination resistors
should not be used.

Auxiliary Power Indication.
AUX_PWR is supported when sampled high and should be
connected using a resistor
JTAG Clock Input
Note: The AUX_PWR/JTAG_TCK port pin includes an internal
pull-down resistor.
NVM Type
The NVM is Flash when sampled LOW and EEPROM when
sampled HIGH.
JTAG TMS Input.
Note: The NVMT/JTAG_TMS port pin includes an internal pull-
up resistor. Also note that the internal pull-up is disconnected
during startup. As a result, NVMT MUST be connected
externally.
JTAG TDI Input
Note: The JTAG_TDI port pin includes an internal pull-up
resistor.
