Bit Name Bit No. Description
BL_FO [7:4] Backlight fade-out rate. The backlight fades from its current value to the off value. The times listed for BL_FO
are for a full-scale fade-out. Fades between closer current values reduce the fade time. See the Automated
Fade-in and Fade-Out section for more information.
0000 = 0.0 sec (fade-out disabled).
0001 = 0.05 sec.
0010 = 0.10 sec.
0011 = 0.15 sec.
0100 = 0.20 sec.
0101 = 0.25 sec.
0110 = 0.30 sec.
0111 = 0.35 sec.
1000 = 0.40 sec.
1001 = 0.45 sec.
1010 = 0.50 sec.
1011 = 0.75 sec.
1100 = 1.00 sec.
1101 = 1.25 sec.
1110 = 1.50 sec.
1111 = 1.75 sec.
BL_FI [3:0] Backlight fade-in rate. The backlight fades from 0 to its programmed value when the backlight is turned on.
The times listed for BL_FI are for a full-scale fade-in. Fades between closer current values reduce the fade time.
See the Automated Fade-in and Fade-Out section for more information.
0000 = 0.0 sec (fade-in disabled).
0001 = 0.05 sec.
0010 = 0.10 sec.
0011 = 0.15 sec.
