Abstract
Digital setting value data, having been stored in a first non-volatile memory in response to the operation of a first switch, is transferred to and memorized in a second non-volatile memory. Stored setting value data is read out from at least one of the first and second memories under the control of an address control circuit and coupled to a digital processing section for carrying out digital arithmetic processing for protective control in the processor.
