I am using i.MX RT1170 UART10 CTS RTS enabled.
Does lpuart driver automatically changes the polarity of CTS/RTS, or do need to do it manually ?
If yes, what are the commands.
Thanks,

Hi @MN19000 ,
If you want to the hardware flow control, and enable the related register, then the UART IP will automatically change the CTS RTS, you don't need to use other other code to control the polarity.
I highly recommend you to read this application note:

This is the related software:

Then you will know the details.
Wish it helps you!
