Abstract
An operation mode setting system is provided in a microprocessor operable in a plurality of operation modes. The operation mode setting system has a signal input line through which an analog voltage corresponding to any of the respective operation modes is applied to an analog-to-digital converter circuit which is built in the microprocessor. The output signal from the analog-to-digital converter circuit is decoded by a decoder, and the microprocessor is set at the predetermined operation mode in response to the decoded output signal.
