Notes: 9. The following signals are tested to 6 mA: FRAME#, TRDY#, IRDY#, DEVSEL#, STOP#, SERR#,
PERR#, and INTA#. All other PCI interface signals are tested to 3 mA.
10. Input leakage currents include hi-Z output leakage for all bi-directional buffers with three-state outputs.
11. For open drain pins, high level output voltage is dependent on external pull-up used and number of
attached gates.
12. Typical values are given as average current with typical SP task execution and data streaming. Current
values vary dramatically based on the software running on the SP.
