5.6.3. Context ID tracing

Context ID tracing is possible only in ETMv1.2 and later.

When a 5-packet address is output that does not have a b000 reason code, a Context ID is traced following the address (provided that ProcIDSize is not b00).

When the Context ID changes, the next branch that occurs (whether direct or indirect) forces the new Context ID to be output.

The packets containing the address and the Context ID must be contiguous, but the continuity bit on the fifth address packet must remain LOW.
