RTS pin direction depends on the selected UART mode. RTS is output in DTE mode and input in DCE mode. Very unfortunate naming;)
IMX53 Reference manual: 76.1.3 table 76-1.
Sorry, i'm here again.
What manual are you using ?
Finding the 'correct' manual seems to quite difficult

"The modem status input signal Clear To Send (CTS) and output modem control line Request
To Send (RTS) are supported."

Must be a fault (bug) into the iMX - processor reference manual (as I expected !)
Thanks for the confirmation .

Hi Andrew,
First of all THANKS for the usefull-reply.
One more question on RTS, when I do read in the DATA-sheets I see that the RTS-pin is specified to be an INPUT, I would expect this to be an OUTPUT.

Hi,
I wonder if you have made any progress on this?
I would like to interface RS485 on the imx53.
In our older boards (none iMX) we use the RTS pin to controll the DRIVER_ENABLE.. would this still be possible ?
Regards Noel
