Quick Start
Complex triggers can be specified by selecting Debug>Complex Trigger
Settings. The Complex Trigger Settings dialog will look different depending on
your selection of:
1. Memory Access
• Program Memory - If a Program Memory access is specified, the trig-
ger can be generated on an instruction fetch or a table read / table write
operation (on PICmicros that have table read / write capability).
• Data Memory - If a Data Memory access is specified, the trigger can be
generated on a read or a write operation.
2. Events
• Sequential - Select Sequential if each event must occur in sequence
to generate the trigger. Keep in mind that for sequential triggers, the
emulator will wait until Event 1 is satisfied before proceeding to Event
2, and on down to the final Trigger event.
• All Events - Select All Events if each event much occur, in any order,
to generate the trigger. The trigger will be generated when the final
event occurs.
• Any Event - Select Any Event if any single event will generate the trig-
ger.
• Time Between Events - Select Time Between Events to specify a
starting and terminating event. This event selection is used in conjuc-
tion with the trace memory window. Up to two events and the start event
can be specified to occur sequentially before the time stamp generator
starts incrementing.
• Filter Trace - Select Filter Trace to specify the events that will be cap-
tured by the trace memory window. Up to three qualifying events can be
specified to occur sequentially before starting to collect the specified
events.To perform a continuous filter trace, check the Infinite Events
checkbox.
Ignore FNOP Cycles should not be specified when performing a Filter
Trace; otherwise, the trace buffer will capture the cycle that executes
after the cycle that caused the trigger.
Note: Processor modules that do not support data monitoring (12-bit
core processor modules) also do not support triggering on data
memory.
Note: Since Ignore FNOP Cycles should not be specified with a Filter
Trace, prefetches will cause the trigger to fire.
