Add ARM ITM Protocol Decoder


J
Jane

An ARM ITM decoder can be used to show trace information from an ARM processor. The trace information is serialized over a single pin using the TPIU. The ITM is useful to show when an exception happens (enter and exit), software trace values (32 channels on the Cortex-M4), PC sampling, etc. Timestamps may also be embedded in the stream.
