Note: Adding bypass capacitors is recommended.
Make sure that GND wiring has only one contact point, and to design the pattern that allows the heat
radiation.
To control setting pins in each mode by SW, make sure to pull down or pull up them to avoid high
impedance.
To input the data, see the section on the recommended input data.
Because there may be shorts between outputs, shorts to supply, or shorts to ground, be careful when
designing output lines, VDD (VM) lines, and GND lines.
