IO出力をするのだが、以下の理由からMIOでなくEMIOを使う。
We need to use the EMIO ports because the MIO locations available to both of the Zynq TTCs are already being used by the Ethernet, USB, and SD Card interfaces.

the waveform output labelled TTC0_WAVE0_OUT.

EMIOはPL側にあるため、
The port we are going to use is not within the Zynq SoC’s PS side. Therefore, we need to create a constraint file to define which pin on the PL side of the device we will use for the TTC waveform output.
