Abstract

PURPOSE:To permit operation despite the occurrence of a fault by loading the microprogram transferred from an upper device onto an RAM when the fault occurs in initial program loading processing. CONSTITUTION:An RAM 2 in which microprograms MP are stored, a microprocessor MPU 1 which executes processing based on the contens thereof, a data transfer control part 5 which intermediates data transfer between the same and an upper device and an MP storage device control part 7 are provided. When a fault occurs in the initial loading processing to be carried out via the part 7, the MPU 1 issues an MP request interruption status to the upper device via the part 5, so that the MP transferred from the upper device is loaded onto the RAM 2.
