No connection
LCD driver supplies voltages. Voltage adjustment pad. Applies voltage between V0 and VSS using a resistive divider. No connection This is the MPU interface switch terminal C86 = “H”: 6800 Series MPU interface C86 = “L”: 8080 Series MPU interface This is the parallel data input/4-line SPI data input switch terminal. P/S = “H”: Parallel data input. P/S = “L”: 4-line SPI data input. No connection This terminal selects the resistors for the V0 voltage level adjustment. IRS = “H”, Use the internal resistors IRS = “L”, Do not use the internal resistors No connection

14. PRECAUTION FOR USING LCD/LCM
After reliability test, recovery time should be 24 hours minimum. Moreover, functions, performance and appearance shall be free from remarkable deterioration within 50,000 hours(average) under ordinary operating and storage conditions room temperature (20+8°C), normal humidity (below 65% RH), and in the area not exposed to direct sun light. Using LCM beyond these conditions will shorten the life time.
Precaution.
