Note
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.
