S32K312 uart的接收（Rx）问题

[haha_123456]

目前是初学，看到uart的example都是使用函数

Lpuart_Uart_Ip_StatusType Lpuart_Uart_Ip_AsyncReceive(const uint8 Instance,
uint8 * RxBuff,
const uint32 RxSize)

和函数

Lpuart_Uart_Ip_StatusType Lpuart_Uart_Ip_GetReceiveStatus(const uint8 Instance, uint32 * BytesRemaining)

来实现uart的Rx来获取或者读取数据，这里需要提前了解数据的长度并且需要等待，我们的真实场景是Rx获取的数据长度是不固定的，有没有检测Rx端有数据的中断或者函数，然后我们通过函数直接去读取，大家有这样的例子吗？

Hi

Please refer to the example in DMA UART IDLE
