Please provide me the sample code for TWIM using the nrfx_twim.h

I am facing the issue while creating the instance using 

/**
* @brief Structure for the TWI master driver instance.
*/
typedef struct
{
NRF_TWIM_Type * p_twim; ///< Pointer to a structure with TWIM registers.
uint8_t drv_inst_idx; ///< Driver instance index.
} nrfx_twim_t;

/**
* @brief Macro for creating a TWI master driver instance.
*/
#define NRFX_TWIM_INSTANCE(id) \
{ \
.p_twim = NRFX_CONCAT_2(NRF_TWIM, id), \
.drv_inst_idx = NRFX_CONCAT_3(NRFX_TWIM, id, _INST_IDX), \
}

Please provide me the syntax for it
