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 nega-
tion 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.
