* to which the GPIO is connected.
* The connected buses differ depending on the various series of MCUs.
* And since the instruction execution clock of the CPU and the bus clock of GPIO are different,
* there is a delay of several clocks to read the change of the input signal.
*
* Define this delay with the GPIO_INPUT_PIN_DELAY macro.
* If the GPIO_INPUT_PIN_DELAY macro is not defined, the following default values will be used.
* (A fairly large value of 0.25 microseconds is set.)
