I read in the TRM of the CC2630 that it is possible to select either normal or reduced slew rate for the GPIO, but unfortunately I cannot find anywhere in the datasheet an indication to what the actual values for these two different modes are.
I currently measure a rise time of about 20ns on a square wave coming out of the GPIO, but I suspect it is slightly faster, as I make this measurement with just a 100MHz scope. I suppose this is the "normal" slew rate, and that the "reduced" one will give us a slower rise time (which is what we want, because we currently get some capacitive coupling between the UART_RX and UART_TX pins and there is some small noise on either of these two lines when the other one is toggling)
Does anybody know where I can find the values for the slew rate settings?
Best regards,
Cristian
