Abstract
When the reset input changes 0 V to Vcc, predetermined operational mode control information is set in an operational mode register (11) to establish a user operational mode. When the reset input changes from 0 V to 2 Vcc, the operational mode control information inputted to a predetermined terminal of the input/output port (25, 58) is set in the operational mode control unit (10a, 10b) to establish a test or other mode.
