Claim Text:
1. A pulse signal outputting apparatus which includes physical amount detecting means for detecting a physical amount, and modulating means for performing pulse modulation on output information obtained from the physical amount detecting means, and which outputs a pulse signal generated by the modulating means, wherein the modulating means includes: wherein the general-purpose input/output terminal is selected as the input terminal by the input/output selecting means when a transition of an output signal level of the pulse signal starts, wherein the pull-up resistor and the general-purpose input/output terminal are connected by the pull-up resistor connecting means when the general-purpose input/output terminal is selected as the input terminal, and wherein the general-purpose input/output terminal is switched to the output terminal by the input/output selecting means after a certain period of time is passed.
