Unless I'm missing something, it appears mspgcc doesn't have support for the second crystal on the 44x devices. Therefore, instead of bitching and whining about it, I decided to write the necessary fixes to make it work. Attached are the necessary fixed files. All I did was add the #define for __msp430_have_xt2 in system_clock.h and in msp430_44x.h. I hope I followed all the necessary conventions observed by the group. Please feel free to modify what I have done. As far as I can tell, this works just fine. I can "turn-on" the XT2 crystal when I want (using the attached code). However, I am apparently unable to turn the XT2 input off. Not sure if this is even possible. The only workaround I have at this time is to hit reset (NMI). I am in communication w/ TI about this and will report as soon as I know something.
