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.
