+    Notes:
+
+    Buttons on the remote are translated into equivalent button presses just
+    as if you were pressing them on the Gigabeat itself.
+    
+    We cannot tell if the hold is asserted on the remote. The Hold function on 
+    the remote is to block the output of the buttons changing.
+
+    Only one button can be sensed at a time. If another is pressed, the button
+    with the lowest reading is dominant. So, if Rewind and Vol + are pressed
+    at the same time, Rewind value is the one that is read.
