Assembly language programming

I've been programming PIC in C and Assembly for many years and I wanted to get started in Cortex-M3. This was a great resource and got me up to speed in no time.

This book is usefully for those , who wants to program Cortex with Keil. I'd like the new edition to have more short examples for better understanding.

I found that this book was lacking in the overview of the Cortex M3 architecture, and in particular the ISA when compared to the free (and authoritative) content found on ARM's web site ("Cortex-M3 Generic User Guide" and, in long form, the "ARMv7-M Architecture Reference Manual") written in a more informative style. After all this is a book on assembly language programming so one can see why the discussion of the ISA and architecture may not be as thorough.
