Signal Quality Specifications
Signals driven on the processor system bus should meet signal quality specifications to ensure that
the components read data properly and to ensure that incoming signals do not affect the long term
reliability of the component. Specifications are provided for simulation at the processor pins.
Meeting the specifications at the processor pins in
ensures that signal quality effects will not adversely affect processor operation.
