TYPE
GoodLink:
This output asserts low if the PENTIC+ is in TPI mode,
link checking is enabled, and the link integrity is good or
if link checking is disabled; otherwise, is not asserted.
This output can also be controlled by power down state
machine; refer to the description of the COR and CFA
registers for more details.
Analog Power Supply Pins:
These pins supply +5V to the PENTIC+'s analog
circuitry for the network interface. Analog layout rules
and decoupling methods must be applied between this
pin and AGND.
Analog Ground Pins:
These pins are the ground to the analog circuitry.
Digital Power Supply Pins:
These pins supply +5V to the PENTIC+'s digital
circuitry.
Digital Ground Pins:
These pins are the ground to the digital circuitry.
