i.MX6ULL UART(RTS CTS)

ban45 — Wed, 09 Jun 2021 02:25:12 GMT

I swapped only CTS and RTS using the CnfigTools for i.MX Version 9.0, but no error or warning. (TX, RX are unchanged)
Which register should be changed to switch the functions in use? Is it possible to replace CTS and RTS without changing TX and RX?

best regard

Hi Yasunori

>Is it possible to replace CTS and RTS without changing TX and RX?

sorry this is not possible. For details one can look at Figure 55-2. UART external signals

to module signals routing with respect to DCE/DTE mode

i.MX 6ULL Applications Processor Reference Manual

Both can be set with the tool.
Do the RTS and CTS listed in the tool mean DCE / DTE = 0?
