ABSTRACT:
A microcomputer which is desired to be small and lightweight comprises an EPROM for storing an operation program for the microcomputer, a selection circuit which opens a gate connected to the ERPOM through the input of an address allocated to the EPROM, and another selection circuit which opens a gate connected to a circuit for storing a fixed value through the input of another address, thus eliminating a verification error which often occurs at the time of writing a program into the EPROM.
