Timing diagrams
The following figure explains the components used in timing diagrams. Variations, when they occur,
have clear labels. You must not assume any timing information that is not explicit in the diagrams.
Shaded bus and signal areas are undefined, so the bus or signal can assume any value within the shaded
area at that time. The actual level is unimportant and does not affect normal operation.
