CC3220SF: UART0_RX Pullup Issues

Part Number: CC3220SF

Hi!

I'm using a uart inferface which is often times not connected to anything causing the pin to collect noise that is being received. The TX line is properly being pulled up to 3.3V, but the RX line is sitting between 1.3V and 1.4V. I need this line to be pulled all the way to 3.3V so that unwanted noise does not trip my program. I've confirmed there is no external circuitry interacting with the RX line that would cause it to float in that range. The only connection is to the microcontroller. I can't seem to find any configuration anywhere to pull up the UART RX line. I'm using the SDK version 2.40.02.00 and would appreciate any help!
