+    The \uicontrol {Peripheral Registers} view displays the current state of
+    peripheral devices, such as a mouse, keyboard, display, printer, or USB
+    drive. Applications write registers to send information to the device and
+    read them to get information from the device. To read registers in a
+    peripheral device, the application accesses its I/O addresses with a load
+    or store instruction that the CPU issues.

+    The \uicontrol Access column shows whether the register is read-and-write
+    (\uicontrol RW), read-only (\uicontrol RO), or write-only (\uicontrol WO).
