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. All inputs that do not include internal pull-ups or pull-downs, must be externally driven for proper
operation. If an input is not driven, it should be tied to power or ground, depending on the particular
function. If an I/O pin is not driven and programmed as an input, it should be tied to power or ground
through its own resistor.
13. 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.
14. Vih for the Joystick position inputs (JACX JACY JBCX JBCY) is dependent on the joystick rate.
