Pin Definitions and Functions
Not Connected Pin
These pins are not bonded with the silicon. Although any potential at
these pins will not impact the device it is recommended to leave them
unconnected. NC pins might be used for additional functionality in later
versions of the device. Leaving them unconnected will guarentee
hardware compatibility to later device versions.
Reserved pins are for vendor specific use only and should be connected
as recommended to guarantee normal operation.
Input is a standard input-only signal.
Totem Pole Output is a standard active driver.
Tri-State or I/O is a bi-directional, tri-state input/output pin.
Sustained Tri-State is an active low tri-state signal owned and driven
by one agent at a time. (For further information refer to the PCI
Specification Revision 2.1)
Open Drain allows multiple devices to share as a wire-OR. A pull-up is
required to sustain the inactive state until another agent drives it, and
must be provided by the central resource.
