SYSTEM FOR CONTROLLING DATA PROCESSING

PURPOSE:To miniaturize the constitution, to shorten an operating time and to improve operability by generating condition data in a condition data generating part, storing these data to a nonvolatile memory, to which an electric writing can not be executed, and referring the data. CONSTITUTION:When interruption is generated, a CPU 1 outputs address data to execute the designation of digital switches 31 and 32 out of digital switches 3 through an address bus 7 and reads the condition number of the 31 and 32 through a data bus 8. This condition number and the condition number of an EEEPROM 6 are caused to be correspondent. The read condition number is held by the CPU 1 and next, the address data of switches 33-37 of the switches 3 are outputted through the bus 7. Then, the condition number of the 33-37 is read through the bus 8. Next, the read condition value is written to an ROM 6 by the CPU 1. On the other hand, when the reference of the condition data is needed, the condition value is read from the prescribed address of the ROM 6 by the CPU 1 and operation control is executed based on the value. Thus, the operating time can be shortened and the operability can be improved.
