LAUNCHXL-CC1350: Output PA/LNA enable on GPIOs

Hello,

Feel like I should know this, but how do I output PA_ENABLE and LNA_ENABLE signals on GPIO pins on the CC1350 so I can measure exact timing for when the radio is in TX/RX?

I looked through the IOCFGx.PORT_ID enumerations but couldn't find it there...

Thanks,

Egil
