Sridhar,

The PC is not available.  Neither are the loop address and subroutine
return addresses.  I believe some of these registers are available via
JTAG, but that probably does not help since JTAG registers are not
memory mapped.  

>From the ADSP-2100 Family User's Manual, page A-11 shows the
non-memory-mapped registers.  Appendix E shows the memory mapped
registers. 

The 219x does allow PC register access.

regards,

Dan Ash

Thanks Dan Ash
I used TOPPCSTACK  instruction and it seems to be sufficient for my
application
