In this LPC11U37FBD48-401 microcontroller from NXP, the pin responsible for reset is called "PIO0_0". According to the project description you've provided, this pin's details are as follows:

So, if you're looking to incorporate a reset functionality into your design, you'd want to connect your reset system to this pin, making sure to design it as active-low according to specifications, because usually reset pins are active-low (This requires confirmation from LPC11U37FBD48-401 datasheet).

To reset the microcontroller, you would typically pull this pin low using a push-button (normally connected to VDD via a pull-up resistor). The exact design of your reset system might also incorporate other elements such as a capacitor for debouncing, depending on your specific needs and the requirements of other components in your system.
