Note: If you do not want your Stack Control information to be saved in the workspace file, you must
modify the default Configuration Setup options by clicking on the Conf... button.
8.7 Trigger/trace settings (DVP emulators)
You can access the Trigger/Trace Settings window either by clicking on (the
Trigger/Trace Settings icon) in the Tools toolbar, or from the main menu by selecting
Tools>Trigger/Trace Settings.
The Trigger/Trace Settings window allows you to set the following modes:
● TRIGIN modes
In the Trigger/Trace Settings window, you may choose the option to Break on
TRIGIN. The TRIGIN port is an input signal port on the DVP board to which you can
connect an external input signal. The Break on TRIGIN option imposes a break in the
running of the program upon reception of a signal rising edge at the TRIGIN pin.
● Trace overflow break mode (DVP2 and DVP3 only)
When the Break on Trace Overflow option is enabled, the program is stopped as soon
as the trace buffer is full (256 records for DVP2 and 512 records for DVP3), otherwise,
the program is not stopped, and only the 256/512 last recorded triggers are kept in the
trace buffer.
● Hardware event mode
For DVP2 and DVP3, there are two hardware event modes: a mode that only influences
the trigger output signal (trace filtering disabled), and a mode where the trace is filtered
using the same hardware events that the trigger acts on.
For DVP1, hardware events only affect the output trigger signals - there is no trace
function available for DVP1. You can either send an output trigger signal in pulse mode,
or you can send a trigger signal in window mode using two event settings:
FORCE_HIGH or FORCE_LOW. For more information, refer to Working with output
triggers (DVP).
8.7.1 Working with output triggers (DVP)
Triggers are output signals that can be connected to an external resource. On the DVP, there
is one output signal pin available called TRIGOUT. This signal can be used to synchronize
