Abstract:
1. A configuration setting device of an integrated circuit, comprising: a signal receiving terminal, for receiving an input signal; a voltage output unit, coupled to the signal receiving terminal, for outputting a voltage signal at the signal receiving terminal according to an enable signal; and a detector, coupled to the signal receiving terminal, for detecting a signal level at the signal receiving terminal and outputting a configuration signal according to the signal level; wherein the input signal is generated outside of the configuration setting device of the integrated circuit, the voltage signal is generated inside of the configuration setting device of the integrated circuit, and the signal level is determined by the input signal or the voltage signal at the signal receiving terminal; wherein the configuration signal is an at least 2-bit configuration signal; and wherein the input signal is operating within a first voltage range, the voltage signal is operating within a second voltage and the first voltage range is larger than the second voltage range.
