Data sheet (SLAS547I) Table 19 contains this information. As far as I know, there's no header file with this since the resolution is done at link time (msp430f2491.cmd).

Rather than typing in a bunch of hex values, it may be simpler to just take the addresses, using the names out of the User Guide (SLAU144J), e.g. "*(volatile unsigned char *)&P1DIR |= BIT0;"

Hallo Mohammed,

when I understand you correctly you are looking for the Port register address:

Can you please check the User guides (SLAU144), Chapter 8.3.

Let me know if that helps

Regards

Kostas
