Instructions:

1. Power-Up Sequence: Ensure that the device is powered up correctly within the specified voltage and temperature ranges.
2. SPI Initialization: Initialize the SPI interface by setting the correct clock polarity (CPOL) and phase (CPHA). The default settings are CPOL = 0 and CPHA = 0.
3. Read Operations: Use the Read Data command (0x03) to read data from the memory. Address should be provided in sequence after the command.
4. Write Operations: Before writing, ensure the Write Enable Latch (WEL) is set using the Write Enable command (0x06). After writing, verify using the Write Status Register (WRSR) command.
5. Erase Operations: Perform sector or bulk erases using the Sector Erase (0x20) or Bulk Erase (0xC7) commands respectively. Ensure no writes occur during erase cycles.
6. Status Check: Use the Read Status Register (0x05) command to check the status of ongoing operations like write or erase cycles.
7. Protect Data: Use the Block Protect bits in the Status Register to protect specific sectors from accidental writes or erases.
8. Handling Power Loss: Implement proper power management to prevent data corruption during unexpected power loss.
