Abstract

In response to determining an event has occurred, information is stored at a trace buffer of an integrated circuit. When the trace buffer is full, execution of instructions at a CPU is halted to allow the trace buffer information to be accessed at an external interface to the integrated circuit device. The CPU is continually halted as the trace buffer is filled to facilitate retrieving all information written to the trace buffer.
