 5Description:
 6		Reading this file returns the stored CIR wakeup sequence.
 7		It starts with a pulse, followed by a space, pulse etc.
 8		All values are in microseconds.
 9		The same format can be used to store a wakeup sequence
10		in the Nuvoton chip by writing to this file.

12		Note: Some systems reset the stored wakeup sequence to a
13		factory default on each boot. On such systems store the
14		wakeup sequence in a file and set it on boot using e.g.
15		a udev rule.
