摘要：
On a single chip microprocessor which has 2.sup.n operation modes, apparatus which permits selecting one mode out of the 2.sup.n operation modes by using only one external pin connection and user program execution. A mode-setting register on the single chip microprocessor can be updated both through the external pin designating one of the two start modes, which are part of the 2.sup.n operation modes, during the reset state of the microprocessor and through a write operation generated by executing a user program during the normal (nonreset) state of the microprocessor.
