Figure 6-1 shows what the tab will look like for a sequential event and program memory
selection. This is the typical layout of the Complex Trigger Settings tab.
FIGURE 6-1:
For information on trigger type (event) selection, see Section 6.6 “Trigger Type
Selection”.
Trace-related trigger information may be entered in the following items:
• Trigger Position – Used to position the trigger location in the trace memory
• Halt On Trigger – The trigger point will generate a hardware breakpoint, halting
• Halt On Cycles After Trigger – The trigger point will not generate a hardware
• Halt On Trace Buffer Full – A trigger will cause the trace buffer to stop before
• Ignore FNOP Cycles – Specifies whether or not forced NOP cycles are to be
window, indicating the number of cycles captured by the trace memory window
after the trigger occurs (Cycles Traced After Trigger). The approximate cycle that
generated the trigger will be indicated with an arrow.

overwriting old data. When the trace buffer is full (64K-1 or 65535 entries), a
hardware breakpoint will halt the processor.
considered in the event processing. A forced NOP cycle is the second cycle of a
two-cycle instruction. Since the PICmicro
prefetches the next instruction in the physical address space while it is executing
the current instruction. However, if the current instruction changes the program
counter, this prefetched instruction is explicitly ignored, causing a forced NOP
cycle.
Note: The number of downloaded lines specified in the Configure Trace tab does
not affect the number of cycles collected, and Trigger Position still applies.
