PORESET to REQ64 hold time
Notes:
1. PCI timing depends on M66EN and the ratio between PCI1/PCI2. Refer to the PCI chapter of the reference manual for a
2. The symbols for timing specifications follow the pattern of t
3. See the timing measurement conditions in the PCI 2.3 Local Bus Specifications .
4. For active/float timing measurements, the Hi-Z or off-state is defined to be when the total current delivered through the
5. Input timings are measured at the pin.
6. The setup and hold time is with respect to the rising edge of PORESET.
