Data Structures
struct	cal_ref_t
	Structure Definition for calref array. More...

struct	operand_t
	The fx20_divide and fx20_multiply uses this structure to pass values into it. More...

Macros
#define	FORCE_ROUND_16 1
	This compile switch used only to experiment with various rounding precisions. The flexibility has a small performance price.

#define	INCLUDE_SI114X_CALIBRATIONCODE 1
	INCLUDE_SI114X_CALIBRATIONCODE should be assigned to 1 for the Si1132, Si1145, Si1146 and Si1147. For the Si1141, Si1142 and Si1143, assign it to 0 to save code space.

#define	INCLUDE_SI114X_COMPRESS_CODE 1
	INCLUDE_SI114X_COMPRESS_CODE should be assigned to 1 for the Si1141, Si1142, Si1143. This switch should be assigned to 0 only if it is certain that the code is not used elsewhere.
