Instructions:

1. Power Supply: Connect the operating voltage between 3.3V and 5.5V to the VCC pin and GND.
2. SPI Interface Setup: Ensure the SPI interface is correctly configured with the microcontroller or control unit.
3. Initialization: Upon power-up, initialize the driver by sending the appropriate commands via the SPI interface.
4. Display Control: Use the serial interface to send data to control the segments and digits of the display.
5. Current Limiting: Set the segment current limit registers to ensure safe operation within the 25mA maximum.
6. Shutdown Mode: To reduce power consumption, use the shutdown mode command when the display is not in use.
7. Temperature Considerations: Operate within the specified temperature ranges to avoid damage or malfunction.
8. Storage Handling: When storing, keep within the storage temperature limits to prevent degradation.

For detailed register settings and command codes, refer to the datasheet provided by the manufacturer.
