12.3.4. FIFO

The trace generated by the PTM is in a highly-compressed form. The trace compression causes the FIFO enable bursts to be flattened out. When the FIFO becomes full, the FIFO signals an overflow. The trace generation logic does not generate any new trace until the FIFO has emptied. This causes a gap in the trace when viewed in the debugger.
