S32K144 MCU is connected to chip with I2C and S32K144 as master ,chip as slave.

Follow is write and read  format:

I have write data to the chip.so I want to read the data that i have writed to the chip.

Follow is my method:

uint8_t Register_Address[1] ={0x36};

uint8_t Rx_buf[1]={0};

uint32_t BytesRemaining;

LPI2C_DRV_MasterSendData(0,Register_Address,1,false);//send internal address

LPI2C_DRV_MasterGetTransferStatus(0,BytesRemaining);//wait ack

if(BytesRemaining == 0)

{

LPI2C_DRV_MasterReceiveData(0,Rx_buf,1, false);

}

But I can't get the data
