CCS/IWR6843: Help trying to use the MSP432 with the IWR6843 using either energia or CCS

Tool/software: Code Composer Studio

Hello,

I am new trying to use the MSP432 and I would like to know if there is a way to interface it with the IWR6843 for a project. I know it is possible using the IWR1443: https://supp.iczoom.com/images/public/20180815/1534314749996089416.pdf 

I assume something similar can be achieved using the IWR6843? Even if there is not an official code on how to achieve this, could I perhaps receive some guidance to perform this task? 

Neither my understanding of ports/pins or of how these devices work is the best, but I thought about using the UART pins to access the data? I have attempted something like this on Energia:

void setup() {
// initialize the digital pin as an output.
Serial.begin(9600);
pinMode(P3_2, INPUT);
pinMode(P3_3,OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
int a = digitalRead(P3_2);
Serial.println(a);


}

On the console I was only getting: "?????????????" 

I do not know how to approach the problem using CCS, so help would be appreciated.

Thank you,

Emmanuel
