4. Enter the counter value.

 

To insert flag actions/events

 

Flags can be used to signal between modules in the logic analysis

 

system mainframe, an expansion frame, or in multiple frames

 

connected with the multiframe module.

 

There are 4 flags that are shared across all connected logic analysis

 

system frames. A flag may be driven or received by multiple modules.

 

Using flags, logic analyzer modules can communicate back and forth

 

with each other multiple times during a data acquisition, both before

 

and after their trigger events occur. (By comparison, the Intermodule

 

window lets one module arm another module one time when its trigger

 

occurs.)

 

By default, flags are cleared. You can insert actions to set, clear, pulse

 

set, or pulse clear a flag. You can insert flag events in different logic

 

analyzer modules to test whether a flag is set or clear.

 

 

NOTE:

In all but the slowest state speed, the logic analyzer can check flags by

 

inserting an event, but cannot change flag status with an action. Flag actions

 

are not available when not using the slowest state speed.

 

A flag that is set by a module remains set until that module clears it. If

 

 

multiple modules set the same flag, all of those modules must clear the

 

flag before it becomes clear.

 

Flags can also be used to drive the logic analysis system's Port Out

 

signal.

 

To insert a flag action

 

You can use the Set/clear/pulse flag trigger function to insert a flag

 

action. When editing advanced trigger functions, follow these steps to

 

insert a flag action:

 

1. In the Trigger tab's Trigger Sequence area, select one of the action buttons

 

(for example, Trigger or Goto), choose Insert ACTION, choose Flag, and

 

choose either Set, Clear, Pulse set, or Pulse clear.

 

Flags in Pulse mode sit in the opposite state when not being pulsed. If you
