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 Further reading on page xx.
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 Further reading
