Hello, NXP support

 

we are using the MPC5746C LINFLEXD in our project, the LIN8 is configured to UART mode.

we now try to use the FIFO for Uart RX, and read the FIFO in ISR.

But seems like the "Data Reception Complete" interrupt didn't trigger if I the RX FIFO mode enabled. please check below screenshot for my debugging.

could you please help me to firgure out how to use interrupt to read data from RX FIFO.
