This is the interface through which the trace data is output for collection. Connect it to ATB compliant trace collection components. Table A.4 shows the ATB master interface signals.
|ATVALIDM||Output||A transfer is valid during this cycle. All other AT signals must be ignored if this is low.|
|ATBYTESM[1:0]||Output||Number of bytes on ATDATA to be captured, minus 1.|
|ATIDM[6:0]||Output||An ID that uniquely identifies the source of the trace.|
|ATREADYM||Input||Slave is ready to accept data.|
|AFVALIDM||Input||ATB flush request. All buffers must be flushed because trace capture is about to stop.|
|AFREADYM||Output||ATB flush acknowledge. Asserted when the buffers are flushed.|
