The LED driver (MSM6731BWAF) corrects the LED illumination by controlling the LED current.
The LED illumination can be set in 16 steps, with 7 steps in the direction of illumination increase
in relation to the standard value, and 8 steps in the direction of decrease. For this reason, the LED
correction data is a 4-bit data for each dot.
The relationship between the LED correction data and LED current correction steps with the LED
driver (MSM6731BWAF) used in an LED head is shown below.
