Abstract: A tristate operating mode setting device is proposed, which is designed for use with an electronic circuit unit for providing the electronic circuit unit with a tristate operating mode setting function, and which is characterized by the utilization of a specially-designed logic circuit and logic control signal generator to allow the electronic circuit unit to be selectively set to one of three different operating modes during startup through a connecting pad that can be externally connected in three different ways. This feature allows one single pad for the provision of three different operating mode settings, whereas prior art is only capable of providing two different settings. The electronic circuit unit is therefore able to use fewer number of pads to provide an increased number of operating mode settings, with the benefit of reducing layout space on circuit board.

Abstract: A function selection system is applicable in an integrated circuit having at least one functional signal line for controlling potential of the functional signal line to select a functionality provided by the integrated circuit. The function selection system at least has a power supply module, a switching module, and a connection module. The power supply module is used to provide power required for operation of the system. The switching module is electrically connected to the power supply module and the functional signal line of the integrated circuit for controlling the magnitude of the current provided by the power supply module flowing through the switching module to be outputted. The connection module is electrically connected to the switching module, the functional signal line of the integrated circuit and a ground terminal, and is used to determine a connection relationship with the ground terminal according to the outputted current magnitude from the switching module. The connection module also controls the output potential of the functional signal line of the integrated circuit through different connection relationships, such that the required functionality can be determined based on the potential of the functional signal line, thereby improving the applicability of the integrated circuit.
