FADE IN / FADE OUT
LP39542 has an automatic fade in and out for main and sub
backlight. The fade function is enabled to main and sub back-
lights with EN_FADE_W1_4 and EN_FADE_W5_6 register
bits. Register bits SLOPE_W1_4 and SLOPE_W5_6 set the
slope of the fade curve. The fading times are shown in the
graphs, which corresponds the full range current change
(0-255). Note that when large display mode is selected (DIS-
PL = 1), then EN_FADE_W5_6 and SLOPE_W5_6 bits do not
have any effect.
