Note: SD_ prefixed pins are for SPI interfaces for multiplexing between SD card socket and FLASH, and they can be
disconnected if they are not in use. F_CS is for flash potential energy (flash chip is reserved and the factory default is not to
be soldered). T_ prefixed pins are for the touch interfaces, and they can be disconnected if they are not in use.

4, Work register configuration description
Tech Support: [email protected]
4.1 Backlight Control
Backlight is driven by 300Hz PWM signals with high energy conversion efficiency and no flicker. When the
backlight register is set to 0, the backlight turns off. When the backlight register is powered up, the reset
value is 0. To avoid blurred screen when powering up, you can clear the screen first when powering up, and
then turn on the backlight. The maximum backlight value is 16 (0x10). When the writing value is greater
than 16, it will be ignored.
4.2 Writing of row and column addresses
The corresponding RAM address of row and column addresses is obtained by internal arithmetic of the control board,
thus users do not need to calculate the correspondence between the row and column addresses and the RAM
address, and they can directly enter coordinates addresses.
4.3 Row and column address increment direction
Row and column address increment direction can be achieved by configuring "address increment direction
register (0x0D)". The address is automatically incremented by 1 when writing continuously. The control
board can be set as the row direction or the column direction address auto increment. When it comes to the
end of the row, it will circulate to the beginning of the row.
4.4 Reading and writing data channel
When reading and writing display data, make sure that the work register value is set to 0x0F and selection
points to data channel; when reading and writing display data, work register cannot be modified to other
values, writing will be failed.
4.5 Resetting and initialization
After the drive board is powered up, RST pin will control resetting. Resetting of low level needs to keep for
1ms to ensure reliable resetting, internal initialization of module can only be done when the resetting pin is
pulled to high level and lasts for 1ms, and then data can be written.
