Homebrew Is it possible to control the notification LED with homebrew?

You know that LED that blinks or shines when you get a Spotpass/Streetpass notification, or if your power is critically low (specifically the one on the N3DS XL)? That's the LED I'm talking about. Would it be possible to control it using homebrew, specifically on 9.2 or below? If so, that seems like it might open up a lot of new possibilities, such as creating custom triggers for certain games. For example, if it was possible, you could create an NTR CFW plugin for Bravely Default that would, say, blink the LED when a building project is done.

Not to mention that it seems to blink in three or four different colors on different occasions. I've looked around in ifixit to see if they mention the LED at all, but no dice, so I'm left wondering if it can only use those colors or if it's an RGB light. If it's an RGB light, then there's even more possibilities.

that would be pretty cool, to have a rainbow led. :V

I don't know enough about the 3ds to judge this but maybe?

Seems promising, the only concern is if something like this would work in sleep mode if it was from, say, a CFW. If not, then it still has it's uses, of course, but even better if it can be used in sleep mode.
