FIFO Overflow Packet
A FIFO overflow packet is generated when a FIFO overflow occurs.
Synchronization Packet
A synchronization packet allows the packet analysis tools to periodically re-align to correct packet
boundaries, because the packet formatter does not maintain 32-bit word boundaries for packets. The
synchronization packet follows the same format as other CoreSight components.
23.3 Signals
The FTM control signals are described in the following sections.
23.3.1 General-Purpose Debug Signals
