CCS/MSP430FR69721: Setting of I/O pin assigned to serial communication

Part Number: MSP430FR69721

Tool/software: Code Composer Studio

Hi everyone,

When I/O pin is assigned to serial communication and the direction is controlled by "eUSCI module", how should the "PxOUT", "PxDIR", and "PxREN" registers be set properly?

Is the initial setting optimal?

Best regards,
