Abstract

PURPOSE: To make it possible to execute a maintenance microprogram by the interrupt of an interrupt generator circuit which is caused by the address coincedence signal generated as a result of comparing contents of a micro instruction address register with those of a stop address register in a comparator circuit.
CONSTITUTION: Memory 11 stores a microprogram and data, and micro instruction address register 12 stores addresses for micro instructions in memory 11 and can set stop address register 16 by the micro instruction. Then, contents of registers 12 and 16 are compared with each other, and the generated address coincedence signal causes interrupt generator circuit 19 to interrupt to a maintenance microprogram, thereby making it possible to execute the maintenance microprogram
