The function ReadSect reads one or more sectors from the FAT Device to a buffer.

The parameter sect specifies the starting sector from where data are read. The parameter buf is a pointer to the buffer that stores the data. The parameter cnt specifies the number of blocks to read.

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

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