Backlight off timeout. After the off timeout (OFFT) period, the backlight turns off. If the dim timeout (DIMT) is
enabled, the off timeout starts after the dim timeout.
0000000 = timeout disabled
0000001 = 1 sec
0000010 = 2 sec
0000011 = 3 sec

Backlight dim timeout. After the dim timeout (DIMT) period, the backlight is set to the dim current value. The dim
timeout starts after the backlight reaches the maximum current.
0000000 = timeout disabled
0000001 = 1 sec
0000010 = 2 sec
