Abstract
In the case of tracing processor activity and generating data streams multiple triggers can be generated at the same time. The issue is further complicated in a protected pipeline where certain locations are considered as in illegal instruction boundary. During those cycles certain information is invalid and cannot be transmitted to the user. Thus a received trace trigger cannot begin. This invention resolves all ambiguities related to multiple triggers so that the user has a known predictable behavior based on the setup of the triggers.
