reflect necessarily the implementation of a pin, e.g. a pin defined of signal type
‘Input’ may be implemented with a bidirectional pad.
Pin Definition and functions
Input is a standard input- only signal.
Totem Pole Output is a standard active driver.
Tri-State or I/O is a bidirectional, tri-state input/output pin.
Sustained Tri-State is an active low tri-state signal owned and driven by
one and only agent at a time. The agent that drives an s/t/s pin low must
drive it high for at least one clock before letting it float. A new agent
cannot start driving a s/t/s signal any sooner than one clock after the
previous owner tri-states it. A pullup is required to sustain the inactive
state until another agent drives it, and must be provided by the central
resource.
Open Drain allows multiple devices to share a line 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.
No-connect Pin n
Such 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. No-connect pins might be used for additional functionality
in later versions of the device. Leaving them unconnected will guarantee
hardware compatibility to later device versions.
Reserved pins are for vendor specific use only and should be connected
as recommended to guarantee normal operation.
