MOTOROLA
The terms assertion and negation will be used extensively.
This is done to avoid confusion when dealing with a mixture of
“active low” and “active high” signals. The term assert or
assertion is used to indicate that a signal is active or true,
independent of whether that level is represented by a high or
low voltage. The term negate or negation is used to indicate
that a signal is inactive or false.
