Abstract
A controller for controlling associated circuitry which includes a microprocessor, read only memory for storing control processes to be run by the microprocessor for controlling the associated circuitry, random access memory, and means for accessing the associated circuitry, by a process which detects changes in the associated circuitry during operation of the associated circuitry, and writes those changes to the read only memory so that they are available to the controller should power be lost during the operation of the associated circuitry.
