Pin Descriptions (Grouped by Function)
An N at the end of a signal name indicates that the active (asserted) state occurs when the signal is
at a low voltage level. When the N is not present, the signal is asserted when it is at a high voltage
level. The terms assertion and negation are used exclusively in order 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.
