Chapter 28: System Test and Debug
The DAP block is an ARM-supplied IP with the following configuration:
• JTAG is the only external interface on chip pinout. Serial wire interface (SW-DP) is not present.
• APB slave and AHB master are the two internal interfaces. JTAG at the DAP's internal side
(JTAG-AP) is present, but only the nSRSTOUT[0] output is connected to the system reset
controller.
• Power-down is not supported.
Note: When JTAG-AP nSRSTOUT[0] is used to assert system reset, DAP is removed from the JTAG
chain. The same sequence for bringing DAP into the chain must be followed again.
28.2.2 Embedded Cross Trigger (ECT)
ECT is the cross-triggering mechanism. Through ECT, a CoreSight component can interact with other
components by sending and receiving triggers. ECT is implemented with two components:
• CTM: Cross Trigger Matrix
• CTI: Cross Trigger Interface
One or more CTMs form an event broadcasting network with multiple channels. A CTI listens to one
or more channels for an event, maps a received event into a trigger, and sends the trigger to one or
more CoreSight components connected to the CTI. A CTI also combines and maps the triggers from
the connected CoreSight components and broadcasts them as events on one or more channels. Both
CTM and CTI are CoreSight components of the control and access class.
ECT is configured with:
• Four broadcast channels
•Four CTIs
• Power-down is not supported.
Table 28-1 lists the connections of trigger inputs and outputs of the CTIs.
