Power Supply Connections
There are two options in providing power to the 82563EB/82564EB:
External LVR Power Delivery
The following power supply requirements apply to designs in which the 82563EB/82564EB is
supplied by external voltage regulators. These systems do not use the internal regulator logic built
into the 82563EB/82564EB as described in
