#include <file_config.h>

BOOL UnInit  (
     void);

The function UnInit de-initializes the SPI serial interface. It is invoked by the function funinit.

Use the function at run-time to disable the embedded Flash or SD Card. Afterwards, invoke only the function finit to re-initialize the drive.

The function is part of the SPI Driver. The prototype is defined in the file File_Config.h. Developers must customize the function.

• __TRUE - on success.
• __FALSE - on failure.
