+port. For example, the base port for the OMAP 2420 provides the <codeph>TOmap::SetRegister()</codeph> and <codeph>TOmap::GetRegister()</codeph> functions
+to access its peripheral controller registers. Peripheral drivers would generally
+use these APIs. Some examples: </p> <ol id="GUID-78156A20-8B2F-52FB-8A9F-159B6EE8714E">
