2.7.9. Coprocessor transfers

Coprocessor transfers (CPRT) do not have an associated data address, so address comparators never match on a coprocessor transfer. When a coprocessor transfer occurs, any address range comparators stop matching.

If CPRT tracing is not supported in the ETM, then coprocessor transfers are ignored by the ETM and the comparator outputs are unaffected by any coprocessor transfers. For more information about the implementation defined features of data value comparators see Data tracing options, ETMv3.3 and later.
