Abstract
Code will switch to secure code via an exception only. All PC and data trace will be turned off during secure code. This will occur regardless of trace being in standard trace mode or event profiling mode. Timing, if on, will switch to standby mode. On return from the secure code, the switches that were already on will switch back and turn on. The address reported in the end sync point will be the address 0x01. Since this is an illegal address, this information is sufficient to indicate an end sync point was caused in secure code.
