- Notify the FTL that the write protection write function is ready

By Hardware - By turning on the hardware switch 

The SSD PCB Features One Hardware Switch 

- Connect to the GPIO pin on the SSD controller

- Detect the GPIO pin signal 

- Notify the FTL that the write protection write function is ready
