CCS/TMS320F28379S: Can I use one SCI module communicate with two devices on two groups of GPIO?

Part Number: TMS320F28379S

Tool/software: Code Composer Studio

 I want to use one SCI module communicate with two devices on two groups of GPIO. Can i?

For example, using SCIB module, GPIO70 and GPIO71 connected with device A, GPIO86 and GPIO87 connected with device B.

So, I can send massages to device A and B. and receive massages by device A and B. Note: device A and B will not send massages at the same time.

When i configure GPIO70, GPIO71 and GPIO86, GPIO87 as SCIB mux selection. Device A and Device B can receive massages from MCU.

But MCU can not receive massages from device A or B.

Can I use one SCI module communicate with two devices on two groups of GPIO?
