AMBA BUS Notes: (From 1999 ARM ihi 0011A Document)

AMBA signal names

         All AMBA signals are named such that the first letter of the name indicates which bus
         the signal is associated with. A lower case n in the signal name indicates that the signal
         is active LOW, otherwise signal names are always all upper case.
         Test signals have a prefix T regardless of the bus type. More information on test signals
         can be found in Chapter 6 AMBA Test Methodology.
