How can I real-time mode debug or do whatever?

Hi, 

I'm using AM3359 processor, CCSv5.2 and I want to write variables during execution program.

But I don't know how I do this!

Every time I want to write variable, I must suspend program and this is so dangerous for my application because it uses high power PWM.

To do this, I read this thread about DAP (http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/p/189774/681339.aspx),

but this procedure isn't useful to me because this is just for watching memory changing.

So.. What can I do for real-time writing without halting program???

Please help me.

Teyun.
