c) Duty Cycle Control

This command sets the duty cycle of the driver output. This command allows the brightness

to be adjusted by 1/32 step. As shown in Figure 1, the blank time between digits or between

the segments is specified by 1 bit time on the hardware. Therefore, the set value ranges from

0 to 31.
