Part Number: MSP430FR5964
Tool/software: Code Composer Studio
since the other thread has been locked ( at https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/929298?CCS-MSP430FR5994-msp430fr5994-h-version-1210-CCS-10-1-0-is-missing-Digital-I-O-Base-Address-Definition )
i will report my comment as a related question:
in our case those port defintions are missing in msp430fr5964.h
to recover i had to install CCS 10.0.0 which contains a version of the header containing the port definitions
CCS 10.1.0 and CCS 10.1.1 is broken.
Although installing the latest Compiler-Updates ends with an Error, i could click refresh in the tools-discovery dialog and the new compiler is registered and i can build.
so this is a working workaround for the time being.
