    so i gone through the specific datasheet for msp430fr6043IPN so i found below information as in picture 

    what i understood from the picture is P2SEL1.x P2SEL0.x = has to be 1 0 (i.e secondary module no need to configure the pin direction right or is must to select pin direction) i need confirmation it is secondary module right?

    PSEL1.x=0 and PSEL0.x=1 (in some data sheets this is abbreviated as PSEL=01) is the Primary alternate function.

    Hi Sandeep,

    You are correct that UCA0TXD is the secondary function, which is enabled for the pin by setting P2SEL1.x to 0 and P2SEL0.x to 1.

    You might find it helpful to start with an example project, or just look at one. We have guided examples, which can be found in the MSP430 Academy, or you can look at some of the uscia uart examples in the MSPWare SDK.
