Detailed Description

•

Cross-triggering

–

Provides a way to propagate debug (trigger) events from one processor, subsystem, or module to

another:

•

Subsystem A can be programmed to generate a debug event, which can then be exported as a

global trigger across the device.

•

Subsystem B can be programmed to be sensitive to the trigger line input and to generate an

action on trigger detection.

–

Two global trigger lines are implemented

–

Device-level cross-triggering is handled by the XTRIG (TI cross-trigger) module implemented in the

debug subsystem

–

For more information about cross-triggering, see section Cross-Triggering in chapter On-Chip

Debug Support of the Device TRM.

•

Suspend

–

Provides a way to stop a closely coupled hardware process running on a peripheral module when

the host processor enters debug state

–

For more information about suspend, see section Suspend in chapter On-Chip Debug Support of

the Device TRM.

•

Processor trace

–

C66x (DSP) processor trace is supported

–

Two exclusive trace sinks:

•

CoreSight Trace Port Interface Unit (CS_TPIU) – trace export to an external trace receiver

•

CTools Trace Buffer Router (CT_TBR) in system bridge mode – trace export through USB

–

For more information, see section Processor Trace in chapter On-Chip Debug Support of the

Device TRM.
