Reset input pin When RSTB is "L", initialization is executed. Register select input pin RS = "H": DB0 to DB7 are display data RS = "L": DB0 to DB7 are Instruction Serial interface selected (PS ="L"); DB6: serial input clock (SCLK) DB7: serial input data (SID) When chip select is not active, DB6 and DB7 may be high impedance. Power supply Ground Voltage converter input/output pin. Capacitor 1 negative connection pin for voltage converter. Capacitor 1 positive connection pin for voltage converter. Capacitor 2 positive connection pin for voltage converter. Capacitor 2 negative connection pin for voltage converter. LCD driver supply voltages. The voltage determined by LCD pixel is impedance-converted by an operational amplifier for application.
