You'll find the info you need in:

   Acorn RISC Machine family Data Manual. VLSI Technology Inc. (1990)
   Prentice Hall, Englewood Cliffs, NJ, USA: ISBN 0-13-781618-9

If you quote these details to your local friendly bookshop, they should be
able to order the manual for you.

(There may by now be a newer version that covers more recent chips such as
the ARM 600 series, the ARM 250 and the new VIDC. Your local VLSI office
could probably advise you on this.)
