can be modified in the NVM. The LED functionality is reflected and can be further
modified in the configuration registers (LEDCTL).

PHY Pins
The 82574 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.
