When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data. When the pin is pulled LOW, the data at D[7:0] will be transferred to a D/C command register. In I2C mode, this pin acts as SA0 for slave address selection. When 3-wire serial interface is selected, this pin must be connected to VSS.

DEP 128128E-Y Production Specification 10. Precautions in use of OLED Modules (1) Avoid applying excessive shocks to module or making any alterations or modifications to it. (2) Don’t make extra holes on the printed circuit board, modify its shape or change the components of OLED display module. (3) Don’t disassemble the OLED display module. (4) Don’t operate it above the absolute maximum rating. (5) Don’t drop, bend or twist OLED display module. (6) Soldering: only to the I/O terminals.
DEP 128128E-Y Production Specification (7) Do not apply stress to the LSI chips and the surrounding molded sections. (8) Do not disassemble nor modify the OLED display module. (9) Do not apply input signals while the logic power is off. (10) Pay sufficient attention to the working environments when handing OLED display modules to prevent occurrence of element breakage accidents by static electricity. * Be sure to make human body grounding when handling OLED display modules.
DEP 128128E-Y Production Specification 10.3 Designing Precautions (1) The absolute maximum ratings are the ratings which cannot be exceeded for OLED display module, and if these values are exceeded, panel damage may be happen. (2) To prevent occurrence of malfunctioning by noise, pay attention to satisfy the VIL and VIH specifications and, at the same time, to make the signal line cable as short as possible. (3) We recommend you to install excess current preventive unit (fuses, etc.
