1st/2nd Gen: Backlight inversion needs to be protected from interrupts, because it can happen any time, even while the greyscale lib or something else is writing to the LCD from an ISR. Also make backlight inversion only hit the LCD if necessary. * Use register definition in the 1st..3rd Gen backlight drivers.
