Notes:
1. The symbols used for timing specifications follow the pattern of t
2. See the timing measurement conditions in the PCI 2.3 Local Bus Specifications.
3. For purposes of active/float timing measurements, the Hi-Z or off state is defined to be when the total current delivered
4. Input timings are measured at the pin.
