The ARMv6-M Architecture Reference Manual is available as download (you'll need to register):
ARMv6-M Architecture Reference Manual
I would recommend the book by Joseph Yiu:
The Definitive Guide to ARM® Cortex®-M0 and Cortex-M0+ Processors: Amazon.co.uk: Joseph Yiu: 9780128032770: Books
(Note: Joseph is a colleague, but that's not why I like the book!)
