Can you please explain how works action CMP_CTRL. What is input/control signal.
Please detail your query. Like which product you are using.
I use EZ-USB® FX3™ Development Kit.
CMP_CTRL is used to compare the data on the control lines with the data that you enter in the CMP_CTRL action settings window (in GPIF II designer). Functionality is simliar to CMP_DATA and CMP_ADDR.
You can get more information from GPIF II designer tool. Open it and press "F1" and then search for "CMP_CTRL" in the search tab of opened window.
