Help

.. code-block:: none

    This option signifies that the CPU implements the Data Watchpoint and
    Trace (DWT) unit specified by the ARMv7-M and above.

    While ARMv6-M does define a "DWT" unit, this is significantly different
    from the DWT specified by the ARMv7-M and above in terms of both feature
    set and register mappings.
