Terminal Function
| Pin No. | Pin Name | Function |
| 1~2 | NC | |
| 3 | /CS1 | This is the chip select signal. |
| 4 | /RES | Rester Pin(L->H) |
5 | A0 | A0 = “H”: Indicates that D0 to D7 are display data. A0 = “L”: Indicates that D0 to D7 are control data. |
| 6 | /WR | Write (/WR ) control signal input. |
| 7 | /RD | Read (/RD ) control signal input. |
8~15 | 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). |
| 16 | VDD | Power supply voltage (Positive) |
| 17 | VSS | Negative power supply,0V |
| 18 | VOUT | DC/DC voltage converter. |
| 19~23 | C3+,C1-,C1+,C2+,C2- | DC/DC voltage converter |
| 24 | NC | |
| 25~29 | V4,V3,V2,V1,V0 | LCD driving voltages. |
30 | VR | Output voltage regulator terminal. Provides the voltage between VSS and V0 through a resistive voltage divider IRS = “L” : the V0 voltage regulator internal resistors are not used. IRS = “H” : the V0 voltage regulator internal resistors are used. |
| 31 | NC | |
32 | C86 | This is the MPU interface selection pin. C86 = “H”: 6800 Series MPU interface. C86 = “L”: 080 Series MPU interface. |
33 | 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. |
| 34 | NC | |
| 35 | IRS | IRS = “H”: Use the internal resistors IRS = “L”: Do not use the internal resistors. |
| 36 | NC |
