* module to user defined settings and default settings, configure the IRQ state
* structure and enable the module-level interrupt to the core, and enable the
* LPUART module transmitter and receiver.
* The following is an example of how to set up the lpuart_state_t and the
* lpuart_user_config_t parameters and how to call the LPUART_DRV_Init function
* by passing in these parameters:
* lpuart_user_config_t lpuartConfig;
