Description
***********



.. code-block:: none

   GPIO pins exposed on Seeeduino Xiao (and compatible devices) headers.

   The Seeeeduino Xiao layout provides two headers, along opposite
   edges of the board.

   Proceeding counter-clockwise:
   * A 7-pin Digital/Analog Input header.  This has input signals
     labeled from 0 at the top through 6 at the bottom.
   * An 7-pin header Power and Digital/Analog Input header.  This
     has three power pins, followed by four inputs labeled 10 at the
     top through 7 at the bottom.

   This binding provides a nexus mapping for 10 pins where parent pins 0
   through 10 correspond to D0 through D10, as depicted below:

       0 D0                     5V   -
       1 D1                     GND  -
       2 D2                     3V3  -
       3 D3                     D10 10
       4 A4                     D9   9
       5 D5                     D8   8
       6 D6                     D7   7

                device that tells the system that the device is capable of
                wake up the system.

                Wake up capable devices are disabled (interruptions will not wake up
                the system) by default but they can be enabled at runtime if necessary.

                The device will be notified when the power domain it belongs to is either
                suspended or resumed.
