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 |
VOUT |
DC/DC voltage converter. |
16~20 |
C3+,C1-,C1+,C2+,C2- |
DC/DC voltage converter |
21~25 |
V4,V3,V2,V1,V0 |
LCD driving voltages. |
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. |
