value. Note that the 82541PI(ER) pin name in the 82541PI(ER) Datasheet/Design Guide is slightly
different from the signal name on the reference schematics. The Datasheet/Design Guide signal
names maintain consistency with the 64-bit gigabit controller naming conventions, while the
schematic names follow the conventions used by our engineers on their design tools.
