... Nomenclature Errata are design defects or errors. These may cause the Intel® PXA255 Processor (PXA255 processor) 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 unless otherwise noted ...
