Release Information
The following changes have been made to this document.
From ARMv7, the ARM architecture defines different architectural profiles and this edition of this manual describes only
the A and R profiles. For details of the documentation of the ARMv7-M profile see Additional reading on page xxiii.
Before ARMv7 there was only a single ARM Architecture Reference Manual, with document number DDI 0100. The first
issue of this was in February 1996, and the final issue, Issue I, was in July 2005. For more information see Additional
reading on page xxiii.
Note
ARM published Issue C of this document, ARM DDI 0406C, in November 2011. That issue incorporates all of the
corrections and enhancements shown in the ARM_2011_Q3 errata mark-up, and can be downloaded from the Infocenter,
http://infocenter.arm.com
. Therefore, ARM will not publish any further errata PDFs for Issue B of the document.
