What information is included in cortex R52 trace

hello_me over 1 year ago

For cortex R52 processor, what does the trace on ATB bus indicate? My understanding is, it is the instruction and data trace.

Example if this is the instruction SUB lr, lr, #4

then opcode of SUB would be on the atbi_data bus and data of lr would be on the atbd_data.

Is that correct?

Tried to correlate the instruction list with the trace on the bus in the waveform but they did not match.
