In the project BF518FEzFlashDriver_M29W320EB, the readme file has the mention below :
"Note that the driver uses software protection if LOCK_CONFIG_FLASH_SECTOR is
defined. This will protect sector 70 from being erased or programmed since
this is where configuration data for the EZ-Board is stored. If you use
a custom driver or remove this protection, you may lose the data that is
programmed in the configuration sector."
What kind of configuration data is stored ?
Which project uses this configuration data ?
What is the risk if this sector is erased ?
