I am trying to use UART on SCB2 with pin P9.3 as CTS on the BLE Pioneer Kit. I have CTS set as active low but it will not transmit when the pin is low. If I set it as active high, it will transmit when the pin is low. Is this how it's supposed to work? I use SCB5 on pins P5.0-3 that is connected to MinProg2 and it transmit with CTS active low when CTS is low. I am connecting the PSoC 6 to a Cypress CYUSBS234 devkit UART port. I have CTS/RTS enabled on both sides. If I set the PSoC 6 RTS pin high or low, the CYUSBS234 transmits in both cases. Isn't it supposed to stop transmission if RTS is high?

Hi,
I think the problem with P9.3 is, that it is not connected to J2 by default, as the 0 Ohm resistor is loaded for Debug Trace Interface.
The second case sounds like the flow control is disabled.
Kind regards,
