Hello

IDLE is set when the LPUART receive line becomes idle for a full character time after a period of activity. After IDLE has been cleared, it cannot be set again until after

a new character has been stored in the receive buffer. I suggest you put a small delay before reading the flag.

If you want to clear the flag I suggest you use the function LPUART_ClearStatusFlag.

Let me know if this is helpful, if you have more questions do not hesitate to ask me.

Best regards,

Omar
