Abstract
An apparatus for and method of providing a data processing system that delays the writing of an architectural state change value to a corresponding architectural state register for a predetermined period of time. This may provide the instruction processor with enough time to determine if the architectural state change is valid before the architectural state change is actually written to the appropriate architectural state register.
