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.
