6.5.3. TFO packet headers

TFO packets are placed in the FIFO by a TFO cycle. The decompressor knows when a packet is placed in the FIFO by a TFO, so TFO packets have their own header byte, as Table 6.6 shows.

Table 6.6. TFO packet header encodings


Normal TFO packet


LSM In Progress TFO packet

[a] RR represents the TFO reason code.

All other encodings are reserved. The TFO packet header encodings are completely independent of the encoding space used by trace data packets.
