********** Directions:
1. Unzip these files into a new directory. 
2. Power up the DSP/AIC12 system 
3. Reset AIC12 through its /RESET hardware pin 
4. Start Code Composer Studio (rev. 2.0 or higher).  
5. Click on the "Project" menu, then click on "Open" menu item.
6. Find the directory where these files are stored in.  
7. Select "AIC12SW_T.pjt", and click "Open"
8. Click on "Project", then click on "Rebuild All"
9. Once the source code is compiled, Click  "File" menu 
10. Click "Load Program" menu item and select "AIC12SW_T.out" to open.
11. Click "Debug" menu, then click  "Run" menu item.

**********
Assuming a speaker has been connected to the standalone slave AIC12's 
output OUTP1/OUTM1, the DTMF or sine tone can be heard. Additionally, 
If a microphone or a signal generator is connected to the AIC12's input,
the signal will be looped back, through the ADC and the DAC of the CODEC,
to the output.

Need a little code change in the file IntrSrvcT.c to select the different
signals (DTMF tone, sine tone, or signal from ADC) to the output.
