10.4.1 Trigger programming examples
The following examples show you how to control the trigger output signals by programming
the Advanced Breakpoints window.
Example 1: Sending a pulsed signal to synchronize an oscilloscope
Sometimes it is useful to send a pulsed signal from one of the output triggers to synchronize
an external device upon the occurrence of a particular event. For example, say that you want
to synchronize an oscilloscope upon the occurrence of an entry into an interrupt loop.
Program your Advanced Breakpoints window as summarized in the table below.
