I keep copies of every document I've needed that I'm allowed to keep as a general rule, including the early paper copies of the ARM architecture reference manual. I even have the original VLSI ARM2 databook. For the ARMv5TE architecture, you're looking for DDI0100E which can be found via google. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 10.2Mbps down 587kbps up
