Claim Text:
1. An integrated circuit with function parameter setting, coupled to an external setting unit, the integrated circuit comprising: a function pin, coupled to the external setting unit; a switch unit, coupled to the function pin; a first function adjustment circuit, coupled to the switch unit, and receiving a reference value, wherein the first function adjustment circuit comprises a first current source and a second current source respectively coupled to the switch unit, the first function adjustment circuit uses the first current source to detect a first voltage detecting value at the function pin, and compares the first voltage detecting value with a default value to generate a comparison result, and controls the switch unit to switch the first current source and the second current source according to the comparison result, and sets a first function parameter; and a second function adjustment circuit, coupled to the switch unit, and detecting a percentage of a divided voltage at the function pin, so as to provide the reference value and set a second function parameter.
