Note 1. See the timing measurement conditions in Figure 9-16.
Note 2. Minimum times are evaluated with same load used for slew rate measurement (as shown in note 3 of Table ); max-
Note 3. Not 100% tested.
Note 4. See the timing measurement conditions in Figure 9-17.
Note 5. PCIRST# is asserted and de-asserted asynchronously with respect to PCICLK (see Figure 9-18).
Note 6. All output drivers are asynchronously floated when PCIRST# is active.
