8.12.2. Special trace source IDs

The following IDs are set aside for special purposes and must not be used under normal operation:

0x00

NULL trace source. Typically this is not used except when draining the formatter where filling of empty locations of frames is required.

0x70-0x7C

Reserved.

0x7D

Trigger event.

0x7E

Reserved.

0x7F

Reserved. This must never be used as a trace source ID because this can cause issues with correctly detecting synchronization packets.
