Abstract: One or more triggers may be coupled to sources on a system on a chip of a portable computing device. The sources monitor the system for status conditions. The one or more triggers are coupled to a trigger bus. A sequencer engine is coupled to the trigger bus and a communication bus. The sequencer engine receives one or more instructions from the communication bus for determining how the sequencer engine should monitor the one or more triggers via the trigger bus and preserve data received from the one or more triggers before a system reset. The sequencer engine then receives data from the one or more triggers and stores the data in local memory storage. The sequencer engine, if programmed, may generate at least one of a trace packet, an interrupt signal, and a general purpose input/output signal in response to receiving data from one or more triggers.
