Table A.5. ATB interface signals
| Signal Name | Description | Direction | Clock Domain |
|---|
| ATDATAM[31:0] | 32-bit trace data. | Output | ATCLK |
| ATIDM[6:0] | Trace source ID. | Output | ATCLK |
| ATVALIDM | ATDATAM is
valid. | Output | ATCLK |
| ATBYTESM[1:0] | Number of valid bytes on ATDATAM. | Output | ATCLK |
| ATREADYM | Indicates that the trace port is able to accept
the data on ATDATAM. | Input | ATCLK |
| AFVALIDM | The FIFO must be flushed. | Input | ATCLK |
| AFREADYM | Acknowledge for AFVALIDM.
