7*02212001SHeiner Kallweit		It starts with a pulse, followed by a space, pulse etc.
8*02212001SHeiner Kallweit		All values are in microseconds.
9*02212001SHeiner Kallweit		The same format can be used to store a wakeup sequence
10*02212001SHeiner Kallweit		in the Nuvoton chip by writing to this file.

12*02212001SHeiner Kallweit		Note: Some systems reset the stored wakeup sequence to a
13*02212001SHeiner Kallweit		factory default on each boot. On such systems store the
14*02212001SHeiner Kallweit		wakeup sequence in a file and set it on boot using e.g.
15*02212001SHeiner Kallweit		a udev rule.
