Instructions:

1. Power Supply Connection: Connect the power supply pins (VDD and GND) to a stable voltage within the specified range of 2.7 V to 5.5 V.
2. SPI Interface Setup: Configure the SPI interface by connecting the appropriate pins (CS, SCLK, SDI, SDO) to your microcontroller or control circuitry.
3. Initialization: Before adjusting the resistance, initialize the device using the SPI commands as per the datasheet.
4. Adjust Resistance: Use the SPI interface to send commands that adjust the wiper position, thereby changing the resistance value between terminals A and B.
5. Endurance Consideration: Ensure that the number of adjustment cycles does not exceed the endurance limit to maintain reliability.
6. Operating Environment: Operate the device within the specified temperature range to ensure optimal performance and longevity.
7. Handling Precautions: Handle with care to avoid damage to the leads and ensure proper soldering if using through-hole termination.
