b) Digit Counter Control
This command sets the number of display digits.
Set the desired number of digits in bits 0 to 3.
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.
