BOOL ECSD_LowLevel_IsCardWriteProtected(void);
Return value
TRUE if the card is write protected, FALSE if not.
If you are communicating with and SD Card that is fixed to the system or through a holder that doesn't support the write protected tab, always return FALSE. Note: You should never call this function directly. The API documentation is present to allow you to write your own low level driver optimized for your hardware.
