1 | VDD | Power supply pin for core logic operation |
2 | VSS | Ground. |
3 | NC(GND) | No connection |
4~11 | D0~D7 | These pins are bi-directional data bus connecting to the MCU data bus. Unused pins are recommended to tie LOW. |
12 | CS# | This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW). |
13 | NC(GND) | No connection |
14 | RES# | This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin pull HIGH during normal operation. |
15 | R/W# | This pin is read / write control input pin connecting to the MCU interface. When 6800 interface mode is selected, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH and write mode when LOW. |
16 | D/C# | This pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data. When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register. |
17 | E | This pin is MCU interface input. When 6800 interface mode is selected, this pin will be used as the Enable (E) signal. |
18 | NC(GND) | No connection |
19 | DISP | No Connection |
20 | NC(GND) | No connection |
21 | TP_INT | Interrupt signal, active low, asserted to request Host start a new transaction |
22 | TP_SDA | I2C data signal |
23 | TP_SCL | I2C clock signal |
24 | TP_RST | External reset signal, active low |
