5.10 External Trigger Signal
(1) External trigger signal input timing
The latch timing of the external trigger signal is shown in Figure 5.3.
Figure 5.3 Latch timing of external trigger signal
(2) External trigger signal input characteristics
Trigger breaks work according to the condition (leading edge/trailing edge) of signals input from
the external trace cable. The external trigger signals of the trace points and the external trigger
signals of the break points use the same signals. The input characteristics of the external trigger
signals are shown in Table 5.3 below. See the table before using external trigger signals.
