IOVCC

Supply voltage(1.65-3.3V).

IM2

Interface selecting signal.

IM1

IM0

RESET

This signal will reset the device and must be applied to properly

initialize the chip.

Chip select input pin (“Low” enable).

fix this pin at VCI or GND when not in use.

DC(SPI-SCL)

-Display data/command selection pin in parallel interface.

-This pin is used to be serial interface clock.

DC=’1’: display data or parameter.

DC=’0’: command data.

-If not used, please fix this pin at VDDI or DGND.

WR(SPI-RS)

-Write enable in MCU parallel interface.

- Display data/command selection pin in 4-line serial interface.

- Second Data lane in 2 data lane serial interface.

-If not used, please fix this pin at VDDI or DGND.

Serves as a read signal and MCU read data at the rising edge.

fix this pin at VCI or GND when not in use.

VSYNC

Frame synchronous signal. Low active.

Connect to I GND when DPI is not selected.

HSYNC

Line synchronous signal. Low active.

Connect to GND when DPI is not selected.

ENABLE

Data enable signal in DPI operation.

Low: Select (Accessible)

High: Not select (Inaccessible)

Connect to GND when DPI is not selected.

DOTCLK

Pixel clock signal. The data input timing is set on the rising edge.

Connect to GND when DPI is not selected.

SDA

Serial data input/output pin in DBI Type C operation.

17~34

DB0~DB17

Data bus.

Connect to GND when is not used.

SDO

This pin is enabled when SDOE=1 and DBI Type C is used. With this

setting, SDA can be used as an input pin and SDO pin can be used

as an output pin without bidirectional bus to exe cute serial

communication.

If not used please open.

LEDA

Anode pin of backlight.

LEDK1

Cathode pin of backlight.
