Abstract:
1. A semiconductor device comprising a generation section and an output section, wherein: the generation section is input with a pulse signal generated in the semiconductor device, a first enable signal asserted when detecting a rise timing of the pulse signal, and is input with a second enable signal asserted when detecting a fall timing of the pulse signal; the generation section generates a first signal that changes in a predetermined direction at a rise timing of the input pulse signal, during a period in which the input first enable signal is asserted and then continues in a changed state for a predetermined duration or longer; the generation section generates a second signal that changes in the predetermined direction at a fall timing of the input pulse signal, during a period in which the input second enable signal is asserted and then continues in the changed state for the predetermined duration or longer; and wherein the output section outputs the generated first signal and the generated second signal to a detection device provided externally to the semiconductor device, the detection device for detecting the pulse width of the pulse signal based on the generated first signal and the generated second signal.
