+Implementation</title><shortdesc>Explains the code you must write to allow users of the GPIO SHAI

+<p>This section is provided to assist platform developers using the GPIO standard
+for communicating with a particular hardware component. It tells you what
+you need to know to produce the hardware specific implementation of the GPIO
+SHAI.</p>
+<p>You provide support for GPIO hardware by providing an implementation of
+the <xref href="GUID-C93C53D3-2BE8-36AE-83B8-4CDB4195649B.dita"><apiname>GPIO</apiname></xref> class which defines methods for pin mode, pin
+bias, debouncing, interrupts, getting and setting pin values and all other
+GPIO functionality that must be coded below the SHAI interface. </p>
