Hello intern.praveena@grinntech.com,
You can call the same LPUART_DRV_SendData and LPUART_DRV_ReceiveData functions to achieve what you want, just keep in mind that the first parameter should be changed to what instance you need it to. You can check out the SDK documentation that is located in: {ROOT_DIR}\doc\Start_here.html .
You can go to S32K144 -> Modules -> Low Power Universal Asynchronous Receiver-Transmitter -> LPUART Driver. Here you can find all the functions that you'll be needing:
So as you can see, you can just change the first parameter (instance) to be 0, 1, or whatever you need it to be (and depending on the hardware, if they are present or not).
Hope this is what you wanted to know. For detailed explanations of the driver you can ask on the S32K community.
Kind regards,
Razvan.
