The ITM is an application-driven trace source that supports printf() style debugging to trace operating system and application events, and generates diagnostic system information. The ITM generates trace information as packets. If multiple sources generate packets at the same time, the ITM arbitrates the order in which packets are output. These sources in decreasing order of priority are the following:
ITM registers are fully accessible in privileged mode. In user mode, all registers can be read, but only the Stimulus Registers and Trace Enable Registers can be written, and only when the corresponding Trace Privilege Register bit is set. Invalid user mode writes to the ITM registers are discarded.
