Terminal Function
| Pin No. | Pin Name | Function |
| 1 | /CS1 | This is the chip select signal. |
| 2 | /RES | Rester Pin(L->H) |
| 3 | A0 | A0 = “H”: Indicates that D0 to D7 are display data. A0 = “L”: Indicates that D0 to D7 are control data. |
| 4 | /WR | Write (/WR ) control signal input. |
| 5 | /RD | Read (/RD ) control signal input. |
| 6~13 | DB0-DB7 | 8bit Date bus, When the serial interface (SPI-4) is selected (P/S = “L”) : D7 :serial data input (SI); D6 : the serial clock input (SCL). |
| 14 | VSS | Negative power supply,0V |
| 15~16 | NC | NC |
| 17 | V0 | When internal DC-DC voltage converter is used, external capacitor is connected between these pins. |
| 18 | XV0 | When internal DC-DC voltage converter is used, external capacitor is connected between these pins. |
| 19~20 | NC | NC |
| 21 | VG | LCD driving voltages. |
| 22~25 | NC | NC |
|
26 |
C86 | This is the MPU interface selection pin. C86 = “H”: 6800 Series MPU interface. C86 = “L”: 8080 Series MPU interface. |
|
27 |
P/S | This pin configures the interface to be parallel mode or serial mode. P/S = “H”: Parallel data input/output. P/S = “L”: Serial data input. The following applies depending on the P/S status:
When P/S = “L”, D0 to D5 must be fixed to “H”. /RD (E) and /WR (R/W) are fixed to either “H” or “L”. The serial access mode does NOT support read operation. |
| 28 | VDD | Positive power supply,3.3V |
