Lighting Data (9 bits)
Lighting is controlled in each line with the values of the load registers. In lighting control, the gradation changes to the specified one at the specified lighting speed
The Lighting speed follows the table below.
The change time is specified with 5 bits;
Note: The change time per 1/15 of brightness represents the time required

spd(4:0)
for a change from, for example, 10/15 to 11/15 of brightness.
The change time from 0/15 to 15/15 of brightness and vice versa rep-
resents the time required for a change from 0/15 of brightness (light
OFF) to 15/15 of brightness (light completely ON). However, these
times are median values and depend on the driving output PWM cycle.
