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.
