Função do pino de interface
Pin No. | Símbolo | Level | DESCRIÇÃO |
---|---|---|---|
1 | P/S | I | This is the parallel data input/serial data input switch terminal. |
2 | C86 | I | This is the MPU interface switch terminal. |
3 | VR | I | Output voltage regulator terminal. Provides the voltage between VSS and V0 through a resistive voltage divider. |
4~8 | V0~V4 | Power supply | This is a multi-level power supply for the liquid crystal drive. |
9 | CAP2N | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2P terminal. |
10 | CAP2P | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2N terminal. |
11 | CAP1P | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal. |
12 | CAP1N | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1P terminal. |
13 | CAP3P | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal. |
14 | VOUT | O | DC/DC voltage converter. Connect a capacitor between this terminal and vss or VDD |
15 | VSS | Power supply | Ground |
16 | VDD | Power supply | Power supply |
17~24 | D7~D0 | I/O | This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus. |
25 | /RD(E) | I | The data bus is in output status when this signal is “L” |
26 | /WR(R/W) | I | The data bus are latched at the rising edge of the WR signal |
27 | A0 | I | This is connect to the least significant bit of the Norman MPU address bus, and it determines whether the data bits are data or a command. |
28 | /RES | I | When RES is set to “L”, the setting are initialized. |
29 | /CS1 | I | This is the chip select signal. |
