The ARM Architecture Reference Manual also known as the "ARM ARM".
Chapter A4/A5 covers instruction encoding. I could not find a direct link
to the latest version that doesn't require a modern browser to
download*. If you don't care about the latest revisions of the ISA maybe
this older version will suffice?
