These pins select interface operation mode Note: Refer to “Interface Selection” for detailed information |
| 14 | RSTB | Reset input pin. When RSTB is “L”, internal initialization procedure is executed |
| 15 | (RD(E/ | (Read / Write execution control pin. (This pin is only used in parallelinterface This pin is not used in serial interfaces and should be connected to VDD1 |
| 16~23 | D7~D0 | The bi-directional data bus of the MPU interface. When CSB is “H”, they are high impedance If using serial interface: D0 is the SDA signal in 4-Line & 3-Line interface D1 is the A0 signal in 4-Line interface |
| 24 | (WR/(R/W/ | (Read / Write execution control pin. (This pin is only used in parallel interface This pin is not used in serial interfaces and should be connected to VDD1 |
| 25 | (A0(SCL | The function of this pin is different in parallel and serial interface In parallel interface: A0 is register selection input A0 = "H": inputs on data bus are display data A0 = "L": inputs on data bus are command In serial interface: this pad will be used as SCL (serial-clock) input |
