2.11.1 Complex Trigger as a Hardware Break Point
Reset the program by selecting Debug>System Reset or by clicking on the
toolbar reset processor icon. This will clear all break points.
To set up the complex trigger, open the Complex Trigger Settings dialog by
selecting Debug>Complex Trigger Settings. Set up the complex trigger so that
it works like the right mouse button complex trigger break point, (i.e., as a
single event sequential trigger at location
0x000A),
with Ignore FNOP
Cycles and Halt on Trigger set (Figure 2.17). Click OK.

The line
movwf PORTB
should have changed color in the source code file
window.
Run the program by selecting Debug>Run>Run or by clicking the toolbar
green stoplight icon. Again, you should see the instruction
movlw 0xFF
of
the
DELAY
routine highlighted, indicating that this is the instruction where
program execution halted, (i.e., there was a 2 instruction skid).
