Image 1: Zoom in right side (top view) of pico-SAM9G45 development board showing J14 connector with PIN1 marked up.
To use these GPIO in software see:
Working_with_GPIOs Working with GPIOs or
Adding a GPIO as a key in kernel or
Adding a GPIO as a led in kernel.
NOTE: WAKEUP/OK has double function, first it acts as normal input, second it is routed to the wake up circuitry of the MCU.
When MCU is in Sleep mode, pressing the WAKEUP/OK button should wake up the MCU.
Pressing the WAKEUP/OK button when the MCU is up, it will act as an OK button.
