Switching Characteristics specify how the processor changes its signals. You have no control over this timing—circuitry external to the
processor must be designed for compatibility with these signal characteristics. Switching characteristics tell you what the processor
will do in a given circumstance. You can also use switching characteristics to ensure that any timing requirement of a device con-
nected to the processor (such as memory) is satisfied.
Timing Requirements apply to signals that are controlled by circuitry external to the processor, such as the data input for a read opera-
tion. Timing requirements guarantee that the processor operates correctly with other devices.
