Hi sergiogv,
You could download the latest version from ARM Information Center: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0419c/index.html
By the way, the book "The Definitive Guide to ARM® Cortex®-M0 and Cortex-M0+ Processors, 2nd Edition" provides also many important information and it is easier to read.
