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:

Kernel_changes_for_custom_hardware#Adding_a_GPIO_as_a_key_in_kernel Adding a GPIO as a key in kernel or

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.
