Chapter 3 Pin Descriptions
Revision 1.0 (02-12-10)
3.1
This chapter is organized by a set of pin configurations followed by a corresponding pin list organized
by function according to their associated interface. A detailed description list of each signal (named in
the pin list) is organized by function in
to
The “N” symbol in the signal name indicates that the active, or asserted, state occurs when the signal
is at a low voltage level. When “N” is not present after the signal name, the signal is asserted when it
is at the high voltage level.
The terms assertion and negation are used exclusively. This is done to avoid confusion when working
with a mixture of “active low” and “active high” signals. The term assert, or assertion, indicates that a
signal is active, independent of whether that level is represented by a high or low voltage. The term
negate, or negation, indicates that a signal is inactive.
