CC1352R: SysConfig Slew Rate Configuration

Part Number: CC1352R
Other Parts Discussed in Thread: SYSCONFIG

Is it possible to configure the slew rate of an output pin using SysConfig? Specifically, I am looking to set the SLEW_RED bit in the IOCFG registers to reduce output slew rate as described in the CC13x2 Technical Reference Manual:

If SysConfig does not support slew rate configuration, how can I enable reduced slew rate while still using SysConfig to generate the rest of the configuration?

Thank you!
Peter

    From syscfg you can configure the GPIO driver but as far as I'm able to see the GPIO driver does to support setting the slew rate. But the pin driver has a define called PIN_SLEWCTRL indicating that if you use the PIN driver you can control the bit you are looking for. The PIN driver is not possible to set from syscfg, you have to add this to the code manually, see the examples in the SDK that are named pin* for how to use and enable this driver.
