Nomenclature

ErrataThese are design defects or errors. Errata may cause the processor’s behavior to deviate from published specifications. Hardware and software designed to be used with any given stepping must assume that all errata documented for that stepping are present on all devices.

Specification Changes – These are modifications to the current published specifications. These changes will be incorporated in the next release of the specifications.

Specification Clarifications – This describes a specification in greater detail or further highlight a specification’s impact to a complex design situation. These clarifications will be incorporated in the next release of the specifications.

Documentation Changes – This includes typos, errors, or omissions from the current published specifications. These changes will be incorporated in the next release of the specifications.

Note:Errata remain in the specification update throughout the product’s lifecycle, or until a stepping is no longer commercially available. Under these circumstances, errata removed from the specification update are archived and available upon request. Specification changes, specification clarifications, and documentation changes are removed from the specification update, when the appropriate changes are made to the appropriate product specification or user documentation (datasheets, manuals, etc.).
