Abstract
A program-controlled unit has debug resources that outputs trace information including selected addresses, data and/or control signals and that can be used to trace the course of the operations occurring within the program-controlled. The debug resources monitor whether a predefined change in the level of one or more predefined bits of the addresses, data and/or control signals contained in the trace information has taken place, and start or terminate the generation of trace information as a function of the result of this check. Additionally or alternatively, the trace information that is output is a component of messages having a variable length portion that contains the trace information. Additionally or alternatively, the trace information that is output is a component of messages, and it is possible to determine which trace information is located at which point within the message.
