摘要：
A semiconductor device includes an external pin, a control parameter decision circuit, and a register update circuit. The control parameter decision circuit includes a register and an output selector. The register is initialized in accordance with resetting of the semiconductor device. The output selector, according to a level value of an external input signal supplied via the external pin, selects one of a signal whose level value is set equal to a register value of the register and a signal whose level value is set opposite to the register value of the register, and outputs the selected signal as a control parameter signal. The register update circuit updates the register value of the register when a level value of the control parameter signal need be changed.
