Abstract
A method and an apparatus for restoring logic states using programming code are disclosed. In one embodiment, the process of a data processing system identifies a first logic value stored in a first register and branches to a first location within the programming code based upon the first logic value. The execution of the programming code occurs in a processor firmware layer. The first register can be used as a scratch register for the subsequent instruction.
