TCK Frequency

You can set the target TCK frequency using the TCK Frequency text box. This frequency is used whilst debugging the chain.

A target TCK frequency is not a guarantee the chain will run at that exact speed. Rather it is only guaranteed it will not exceed it. It may run slower due to other factors in the project setup or the type of JTAG controller used at runtime.

In XJDeveloper, XJInvestigator or when an XJPack file is opened this option is not present. Instead, the TCK Frequency should be set through the Advanced Configuration Options tab.
