The list below shows all available trace filtering and trigger actions:
<action>
Behavior
TraceEnable
Configure the trace source to only generate a trace message if the
specified event occurs. Complete program flow or data trace is disabled. If
more than one TraceEnable action is set, all TraceEnable actions will
generate a trace message. See
TraceON
TraceOFF
If the specified event occurs, program and data trace messaging is started
(TraceON) or ends (TraceOFF). In order to perform event based trace
start/end to program trace and data trace separately, use Alpha-Echo
actions.
TraceTrigger
Stop the sampling to the trace on the specified event. A trigger delay can
be configured optionally using
BusTrigger
If the specified event occurs, a trigger pulse is generated on the podbus
trigger line. This trigger signal can be used to control other podbus devices
(e.g. PowerProbe) or to control external devices using the trigger
connector of the PowerDebug/PowerTrace module (see
).
BusCount
The specified event is used as input for the counter of the
PowerDebug/PowerTrace module. See
for more information.
WATCH
Set a watchpoint on the event. The CPU will trigger the EVTO pin if the
event occurs and generate a watchpoint hit message if the trace port is
enabled.
Alpha - Echo
Declares an event for several special control / trigger actions:
•
Configure event triggered trace start/end for program and data
separately. See
for details.
•
Configure Trace/Trigger events for additional nexus trace clients.
See
for details.
•
Configure event triggered performance counter start/stop. See
for details.
•
Configure trigger events for the complex trigger unit. See
Trigger Unit for Nexus MPC5xxx”
details.
NOTES:
•
TraceEnable action on data address uses the data address selectors
of the NEXUS module, no watchpoints are used in this case.
•
Actions on data address (excluding TraceEnable) can not differentiate
between read and write access. Only /ReadWrite is allowed.
