8-15 | D7-D0 | I/O | 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. |
||||||||||||
I | 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. |

16 | ERD | I | Read/Write execution control pin. When PSB is “H”,
ERD is not used in serial interface and should fix to “H” by VDD1 or VDDH. |
||||||||||||
17 | RWR | I | Read/Write execution control pin. When PSB is “H”,
RWR is not used in serial interface and should fix to “H” by VDD1 or VDDH. |
||||||||||||
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. |
