عملکرد پین رابط
Pin No. | Symbol | Description |
1 | VDD | Power supply |
2 | NC | No connection |
3 | VSS | Ground |
4 | CSB | Chip select input pin CSB=“L”: This chip is selected and the MPU interface is active CSB=“H”: This chip is not selected and the MPU interface is disabled (D[7:0] are high impedance) |
5 | RSTB | Reset input pin. When RSTB is “L”, internal initialization procedure is executed |
6 | E | Read / Write control input pin. R/W = “H”: When E is “H”, data bus is in output status. R/W = “L”: The data are latched at the falling edge of the E signal. |
7~14 | D7~D0 | The bi-directional data bus of the MPU interface. When CSB is “H”, they are high impedance |
15 | R/W | Read / Write control input pin R/W = “H” : read R/W = “L” : write |
16 | A0 | 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 |
17 | A | LED+ |
18 | K | LED- |
