DCACHE

The type DCAHCE describes the data sector caching structure. The structure is defined in the file File_Config.h as follows:

typedef struct dcache {
  U32 sect;                             /* Working Data sector number        */
  U32 csect;                            /* Data Cache starting sector number */
  U8  *buf;                             /* Working Data sector buffer        */
  U8  *cbuf;                            /* Data Cache sector buffer          */
  U8  nwr;                              /* Number of buffered write sectors  */
  U8  nrd;                              /* Number of cached read sectors     */
} DCACHE;

Example:

#include <file_config.h>
...
DCAHCE dataCache;
...
  dataCache.sect  = 20;
