| 3 | VG | VG is the LCD driving voltage for segment circuits | ||||||
| 4 | XV0 | XV0 is the LCD driving voltage for common circuits at positive frame. | ||||||
| 5 | V0 | V0 is the LCD driving voltage for common circuits at negative frame. | ||||||
| 6 | VSS | GROUND | ||||||
| 7 | VDD | POWER | ||||||
| 8 | SDA | D[1:3] must be connected together as SDA. D[4:7]=(1,1,1,1): ID Pin. D[4:7] should fix to “H” or “L” by VDDH or VSSL. |
||||||
| 9 | SCL | |||||||
| 10 | A0 | It determines whether the access is related to data or command. A0=“H” : Indicates that signals on D[7:0] are display data. A0=“L” : Indicates that signals on D[7:0] are command. |
||||||
| 11 | RSTB | Hardware reset input pin. When RSTB is “L”, internal initialization is executed and the internal registers will be initialized. | ||||||
| 12 | CSB | Chip select input pin. Interface access is enabled when CSB is “L”. When CSB is non-active (CSB=“H”), D[7:0] pins are high impedance. |
