Can you please send me the AMBA APB 3.0 specification for reference.
These AMBA documents can only be downloaded from the ARM websites after you have agreed to some conditions of use, so they cannot be emailed.
Please go to the following website where, if I have copied the correct link, you should see links to each AMBA spec download area.
