15.5. ETM architecture

The ETM is an instruction only ETM that implements ARM ETM architecture v3.4. It is based on the ARM ETM Architecture Specification. For full details, see the ARM Embedded Trace Macrocell Architecture Specification.

All Thumb-2 instructions are traced as a single instruction. Instructions following an IT instruction are traced as normal conditional instructions. The decompressor does not have to refer to the IT instruction.
