<blockquote type=cite class=cite cite=""> Hi. I'm
looking for suggestions of good ways to read the MSP-430<br>

various<br>
approaches:<br><br>
1) Using inline asm ala: asm("mov r2,%saveSR")<br><br>
This doesn't work since the function it is called from is complex and
the<br>
compiler apparently can't free up a register to store the local
variable<br>
saveSR in.</blockquote><br>
Define a variable in a fixed location of memory and move to
that:<br><br>
<font size=3>#pragma abs_address 0x200<br>
unsigned int sr_copy;<br>
#pragma end_abs_address<br><br>
asm("mov r2, &0x200");<br>
