Hi Venkat!

If you're using version 2 of the IAR tools then you can use the
"asm"
keyword to mix assembler instruction and C code.

For example:

void test()
{
  asm("NOP");
}


This results in the following code:

      1          void test()
   \                     test:
      2          {
      3            asm("NOP");
   \   000000   0343                 NOP
      4          }
   \   000002   3041                 RET

You'll have to buy it!

Or use an all-free solution like http://mspgcc.sourceforge.net/ (gcc 
port, does inline "asm" nicely) together with your favorite source 
code editor (www.scintilla.org?) and a good JTAG uploader & debugger 
like NoICE430 (freeware at http://www.noicedebugger.com/, others seem 
to sell it for >200EUR, strange...). 

Of course, you could also continue using the free IAR IDE from TI as 
a source code editor and C-spy for uploading, but compile the stuff 
using msp430-gcc (to get past the 4kB obj code limit and the strange 
IAR C "interpretations" and ASM restrictions)

NoICE430 is not freeware. There is a demo version but it is not free. In 
the ideal world, everyone has a day job programming and consulting and then 
work at their favorite GPL projects at night. Of course if all SW are GPL, 
then what would they work on during the days :-) Anycase, ImageCraft paid 
for the development of NoICE430, and seeing ImageCraft doesn't have as many

people and money as, oh, say, TI, we would like to recoup the money. It's 
not > 200 Euro, but $100.

There are at least three 3rd party tool developers that are active in
this group:

Imagecraft
Quadravox
Rowley Associates

I've tried all of them and wouldn't hesitate recommending any of them
for
professional work. All of their tool sets are less expensive than IAR's and
(IMHO) all are better quality tools and a better value. They are also very
responsive with technical support/bug fixes.

If you are doing real "paying" projects, then I think supporting a
tool
vendor is a good thing. If you are doing small educational projects, TI's
limited version of the IAR Workbench (4K for the C compiler, unlimited
assembler) might be acceptable. It's available from TI's web site or
distributed on their MSP430 CDROM.

Of course, if you want free you can always go with the GNU tools.

One of the things that I've been pleasantly surprised with is the
availability
of high quality, moderately priced development tools for the MSP430 family.

I just want to second Matt's comments.  We use the Quadravox product. 
The
quality is very good, the price is right, the licensing rules and
enforcement are reasonable and the support is OUTSTANDING!

If you want to make sure that its the right product for you, the Quadravox
comes with a 30 day free trial, just download the tool and go to town.

The help screens provided with the tool include detailed notes on the
compatibility issues between Quadravox and IAR, BTW for my money, Quadravox
made much better decisions about how to implement the non-standard features
of the compiler than IAR.

Hope this helps.

cheers,
