Minimum "system" IALG_Cmd value.

#define IALG_EOK   0

Successful return status code.

#define IALG_EFAIL   -1

Unspecified error return status code.

#define IALG_MPROG   0x0008

Program memory space bit.

External memory space bit.

#define IALG_isProg

(

s

)

Value:

(        \
    (((int)(s)) & IALG_MPROG)   \
)

#define IALG_isOffChip

(

s

)

Value:

(     \
    (((int)(s)) & IALG_MXTRN)   \
)

Typedef Documentation

typedef struct IALG_Obj* IALG_Handle

Handle to an algorithm instance object.

typedef unsigned int IALG_Cmd

Algorithm specific command.

Remarks:

This command is used in conjunction with IALG_Status to get and set algorithm specific attributes via the algControl() method.
