Abstract

A state sensitive device is described, the device including a state register which stores a record of the effective-state of the device, a mask field having a value which varies according to a value of the state register, and a processor which changes the value of the mask field to a new value of the mask field when there is a change in the value of the state register, wherein, the processor performs a state dependent calculation requiring the value of the mask field as an operand in the state dependent calculation which will yield an incorrect result if the value of the mask field does not properly correspond to the value of the state register. Related methods, systems and apparatus are also described.
