I see. From my understanding, the sample code that is on the website for this S08PT60 EVK is for the accelerometer and RGB LED sample application. Therefore, the LED should change the color when you move the board. Also, this means that this code is not for the touch sense input, I already validate the code and the Touch sense ports are not setup. In addition, the TSI is also not included in this sample code which could be the reason why the TSI and the Touch sense inputs are not working.
You may need to create a new project for this MCU or edit the sample code to setup the TSI and touch sense inputs correctly.
