Abstract
The present invention provides a control signal generating circuit, which comprises a signal output module comprising an output terminal, a first control signal input terminal and a second control signal input terminal, and the signal output module can selectively output the first control signal input from the first control signal input terminal or the second control signal input from the second control signal input terminal to a control signal receiving circuit via the output terminal. The present invention further provides a circuit system comprising the control signal generating circuit. When providing high-level signal and low-level signal for a control signal receiving circuit, the control signal generating circuit of the present invention only needs to switch between first control signal mode and second control signal mode, without complicated conversion. In addition, the control signal generating circuit of the present invention can test various control signal receiving circuits which need quick action.
