Description of the EE-Note:

 This EE-Note describes how to program the core phase-locked loop (PLL) on ADSP-2126x, 
 ADSP-2136x, ADSP-2137x, and ADSP-214xx SHARC processors. It also provides example code  
 for programming the PLL and discusses possible problems that can occur due to incorrect 
 programming. It also discusses about some debug techniques which help for correct PLL 
 handling. C callable library functions for programming the PLL on all processors
 are also provided with this document. The library functions can be added to the C run-time
 library and called from VisualDSP++ project files.

1. 2126x - This folder has the initPLL_2126x.asm source file, object file and the header file
	   for ADSP-2126x processors.
2. 213xx - This folder has the initPLL_21362.asm, initPLL_21368.asm and initPLL_2137x.asm source
 	   files, and the header file for ADSP-213xx processors.
3. 214xx - This folder has the initPLL_2146x.asm,initPLL_2146x_anomaly_15000020_Workaround.asm,
	   initPLL_2147x.asm,initPLL_2147x_anomaly_15000020_Workaround.asm,initPLL_2148x.asm and 
	   initPLL_2148x_anomaly_15000020_Workaround.asm source files and the header file for ADSP-214xx
	   processors.
4. Testcodes - This folder has example codes for using the initPLL library functions for ADSP-2126x, 
	   ADSP-2136x, ADSP-2137x and ADSP-214xx processors.
