Note 2: Power & Ground
There are two GND and two VDD rails internally. One set of rails supply power and ground to output buffers while in switching
state (called AC power) and another rail supply the core logic, input buffers and output buffers in steady-state (called DC rail).
The rails are not connected internally. This precaution reduces the effects of simultaneous switching outputs and undesirable RF
radiation fromthe chip. Further precaution is taken by segmenting the GND and VDD AC rails to isolate the PCI, Local Bus and
UART pins.
