9.10. Trace data storage

Data is received by the ETB ATB Formatter block. When TraceCaptEn is asserted the Formatter starts the process of embedding the source IDs into the data stream, or normal mode, then outputs 32-bit words to be stored in the ETB Trace RAM. When data is ready to be stored in the Trace RAM, data is written to at the address stored in the RAM Write Pointer Register. When the Trigger Counter Register reaches zero, the acquisition complete flag AcqComp is asserted and trace capture is stopped.
