摘要
An electronic apparatus is disclosed, where the apparatus revises the micro-program thereof reliably. The apparatus provides a master and slave CPUs each having a memory. The micro-program to be revised is temporarily set in the memory of the slave CPU. Interrupting the master CPU, and connecting the slave CPU with the master CPU via an auxiliary interface independent of the inner interface (bus), the micro-program to be revised and stored in the memory of the slave CPU is transferred to the memory of the master CPU through the auxiliary interface. Auxiliary interface is cut during the normal operation of the master CPU.
