+Description:
+ Reading this file returns the stored CIR wakeup sequence.
+ It starts with a pulse, followed by a space, pulse etc.
+ All values are in microseconds.
+ The same format can be used to store a wakeup sequence
+ in the Nuvoton chip by writing to this file.
+
+ Note: Some systems reset the stored wakeup sequence to a
+ factory default on each boot. On such systems store the
+ wakeup sequence in a file and set it on boot using e.g.
+ a udev rule.
