Instructions:

1. Power Supply Connection:

   • Connect Vcc to the power supply within the specified voltage range.
   • Connect GND to the ground.

2. SPI Interface Configuration:

   • Connect the MOSI pin to the master's data output.
   • Connect the MISO pin to the master's data input.
   • Connect the SCK pin to the master's clock.
   • Connect the CS pin to the master's chip select signal.

3. Initialization:

   • Ensure that the CS pin is high when not communicating.
   • Begin communication by pulling the CS pin low.

4. Read/Write Operations:

   • Use standard SPI commands for read and write operations.
   • For writing, ensure the device is not write-protected and wait for the write cycle to complete before issuing new commands.

5. Handling Care:

   • Avoid exposing the device to temperatures outside the operating range.
   • Ensure proper decoupling capacitors are placed near the power pins to stabilize the supply voltage.

6. Storage Conditions:

   • Store in a dry, cool place away from direct sunlight and sources of heat or moisture.
