| 6 | VSS | This is a 0V terminal connected to the system GND. | |||||||||||||
| 7 | VDD | Shared with the MPU power supply terminal VDD. ( 3.3 V ) | |||||||||||||
| 8 | D7 | When using 8-bit parallel interface: (6800 or 8080 mode) 8-bit bi-directional data bus. Connect to the data bus of 8-bit microprocessor. When CSB is non-active (CSB=“H”), D[7:0] pins are high impedance. When using serial interface: 4-LINE D7=SDA : Serial data input. D6=SCL : Serial clock input. D[5:0] are not used and should connect to “H” by VDD1 or VDDH. When CSB is non-active (CSB=“H”), D[7:0] pins are high impedance. |

| 18 | A0 | I | 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. |
||||||||||||
| 19 | RSTB | I | Hardware reset input pin. When RSTB is “L”, internal initialization is executed and the internal registers will be initialized. |
||||||||||||
| 20 | CSB | I | 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. |
