ELECTRICAL CHARACTERISTICS IN A/A MUX MODE: Certain specifications differ

from the previous sections, when programming in A/A Mux Mode. The following subsec-

tions provide this data. Any information that is not shown here is not specific to A/A Mux

Mode and uses the FWH Mode specifications.

Notes:

1. Input leakage currents include high-Z output leakage for all bi-directional buffers with tri-state outputs.

2. Refer to PCI spec.

3. Inputs are not “5-volt safe.”

Notes:

1. If RST is asserted when the WSM is not busy (RY/BY = 1), the reset will complete within 100 ns.
