Introduction
Signal Type Definition:
The following signal type definitions are mainly taken from the PCI Specification
Revision 2.1:
in
Input is a standard input-only signal.
out
Totem Pole Output is a standard active driver.
t/s, I/O
Tri-State or I/O is a bi-directional, tri-state input/output pin.
s/t/s
Sustained Tri-State is an active low tri-state signal owned and driven
by one and only one agent at a time. (For further information refer to
the PCI Specification Revision 2.1)
o/d
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.
