*These values do not include any statistical spreads and are suitable for indications only.
**Values have been measured from a few samples running under the following conditions:
1) 3.3v PCI Environment.
2) PCI CLK active, SYSTEM CLK line driven by a crystal or clock module.
3) All PCI configuration accesses over.
4) Single UART channel (1 COM port) set to operate at the maximum data-transfer rate,
with it’s internal loop-back enabled.
5) Values measured during file transfers (at the max rate)
