it is a rising edge or a falling edge. If a number of edges are collected at instances

• Jitter — Any timing variation of a transition edge or edges from the defined Unit
Interval.
• Storage Conditions — Refers to a non-operational state. The processor may be

exposed to free air. Under these conditions, processor lands should not be
connected to any supply voltages, have any I/Os biased, or receive any clocks.
