Vector catch is a mechanism used to trap processor exceptions. This feature is typically used in the early stages of development to trap processor exceptions before the appropriate handlers are installed. You select the vectors to trap by setting the vector_catch value to True, and configuring the required exceptions in the Vectors group.

You can set the vector catch settings from various places in the debugger, including the Connection Properties window. However, see Avoiding conflicts between linked board groups for the implications of changing settings in more than one place.
