Note 1. Clock frequency is between nominal DC and 33 MHz. Device operational parameters at frequencies under 16 MHz
are not 100% tested. The clock can only be stopped in a low state.
Note 2. Guaranteed by characterization.
Note 3. Slew rate must be met across the minimum peak-to-peak portion of the clock waveform (see Figure 9-15).
Note 4. The minimum PCIRST# slew rate applies only to the rising (de-assertion) edge of the reset signal. See Figure 9-19
for PCIRST# timing.
