LM75A Temperature Sensor with I2C Communication

Hello Dear,

I want to sample code for i2c temperature sensor with RL78 family(R5F10NME). I tried using code generator but not working. 

I couldn't find any sample code where these functions are used.
R_IIC00_Master_Send,R_IIC00_Master_Receive;

Please help me.
Thanks a lot.

My Code is below here:

static const uint8_t DEVICE_ADDR= 0x48 << 1;
static const uint8_t REG_TEMP = 0x00;

uint8_t buf[11];
uint8_t tempval[2];

while()

{

buf[0] = REG_TEMP;
R_IIC00_Master_Send(DEVICE_ADDR,buf, 1);

R_IIC00_Master_Receive(DEVICE_ADDR, tempval, 2);

}

//CODE GENERATOR

void R_IIC00_Master_Send(uint8_t adr, uint8_t * const tx_buf, uint16_t tx_num)
{
g_iic00_master_status_flag = _00_SAU_IIC_MASTER_FLAG_CLEAR; /* clear IIC00 master status flag */
adr &= 0xFEU; /* send mode */
g_iic00_master_status_flag = _01_SAU_IIC_SEND_FLAG; /* set master status flag */
SCR00 &= (uint16_t)~(_C000_SAU_RECEPTION_TRANSMISSION);
SCR00 |= _8000_SAU_TRANSMISSION;
/* Set paramater */
g_iic00_tx_count = tx_num;
gp_iic00_tx_address = tx_buf;
/* Start condition */
R_IIC00_StartCondition();
IICIF00 = 0U; /* clear INTIIC00 interrupt flag */
IICMK00 = 0U; /* enable INTIIC00 */
SIO00 = adr;
}

void R_IIC00_Master_Receive(uint8_t adr, uint8_t * const rx_buf, uint16_t rx_num)
{
g_iic00_master_status_flag = _00_SAU_IIC_MASTER_FLAG_CLEAR; /* clear master status flag */
adr |= 0x01U; /* receive mode */
g_iic00_master_status_flag = _02_SAU_IIC_RECEIVE_FLAG; /* set master status flag */
SCR00 &= (uint16_t)~(_C000_SAU_RECEPTION_TRANSMISSION);
SCR00 |= _8000_SAU_TRANSMISSION;
/* Set parameter */
g_iic00_rx_length = rx_num;
g_iic00_rx_count = 0U;
gp_iic00_rx_address = rx_buf;
/* Start condition */
R_IIC00_StartCondition();
IICIF00 = 0U; /* clear INTIIC00 interrupt flag */
IICMK00 = 0U; /* enable INTIIC00 */
SIO00 = adr;
