The 'GPIO' project is a simple program for the MAX32660
microcontroller using the Maxim Integrated MAX32660 Evaluation
Kit.

Example functionality:
 - Uses GPIO
 - The example reads P0.12 (S1) and outputs the input value onto
    P0.13 (DS1).
 - Uses the GPIO IRQ and responds to events on P0.3.
   - When P0.3 changes state, the IRQ toggles P0.2
 - Status is transmitted via stdout using UART0 to
   a host terminal at 115,200 Baud, 8N1.
