If you have enabled the SoftDevice you can use sd_nvic_systemreset(), if not you can use nvic_systemreset()

ret_code_t mma8452_I2C_register_read(uint8_t slave_addr, uint8_t reg_addr, uint8_t * pdata, uint32_t bytes) {
ret_code_t ret_code;

    ret_code = nrf_drv_twi_tx(p_twi_master,slave_addr, &reg_addr,1,true);
    
    if(ret_code != NRF_SUCCESS)

but when i put break point on *x = (rx_buffer[0]) it goes into infinite loop

hello i am interfacing i2c sensor mma8452 with nrf51 dk. my function is

void mma_read(uint8_t *x, uint8_t *y, uint8_t *z)
{
    uint32_t err_code;

    uint8_t rx_buffer[6];
    
    err_code = mma8452_I2C_register_read(MMA_ADDR, DATAX0, rx_buffer, sizeof(rx_buffer)); 

    if(err_code != NRF_SUCCESS)
		{
		sd_nvic_SystemReset();
		}
	  *x = (rx_buffer[0]);
   *y = (rx_buffer[2]);
  *z = (rx_buffer[4]);

}

If you are using a SoftDevice you can use sd_nvic_systemreset()
