Table 34 describes the XTI registers.

XTI peripheral is declared in the 71x_map.h file as follows

/* APB2 Base Address definition */

#define APB2_BASE 0xE0000000

/* XTI Base Address definition */

#define XTI_BASE

(APB2_BASE + 0x101C)

/* XTI peripheral pointer declaration*/

#ifndef DEBUG

EXT XTI_TypeDef *XTI;

...

#else

#define XTI ((XTI_TypeDef *) XTI_BASE)

...

#endif

When debug mode is used, XTI pointer is initialized in 71x_lib.c file:

#ifdef _XTI

XTI = (XTI_TypeDef *)XTI_BASE;

#endif /* _XTI */

In debug mode, _XTI must be defined, in 71x_conf.h file, to include the XTI library

#define _XTI
