Figure 60: Capture View
The user must determine which signals are used to enable, activate, and then reset the Capture component. A CaptureTriggered destination
is then available to indicate to the user that data has been captured and is available for use.
Figure 61: Capture Component
A detailed description of all the Capture parameters is below.
CaptureEnable
The CaptureEnable is used to enable or “arm” the capture component. If the CaptureEnable is not active, then the CaptureActivate has no
effect, and the CaptureTriggered remains inactive. Once the CaptureEnable is activated, the Capture component is ready and waiting for a
CaptureActivate signal to capture data. CaptureEnable is a read-only destination on the Assignments view, and is accessible through a user
program.
CaptureActivate
If the Capture component is enabled and has been reset (CaptureTriggered is inactive), then the rising edge of CaptureActivate will capture
the four data parameters and cause CaptureTriggered to be activated. If the Capture component is not enabled, or has not been reset, the
CaptureActivate will be ignored.
CaptureReset
The CaptureReset is used to reset or re-arm the capture component after it has been activated. If the capture has been activated, the
CaptureTriggered destination will be active. The capture component cannot capture data again until it has been reset. The capture
component will automatically reset itself if the CaptureEnable signal is removed.
CaptureTriggered
The CaptureTriggered signal is read-only and indicates that the Capture component was activated and that data has been captured.
CaptureTriggered will activate on the leading edge of CaptureActivate if the Capture component is enabled and reset. Capture Triggered will
remain active until CaptureReset is activated.
