C5.6 Behavior of non-invasive debug in Debug state<br />

Debug State<br />

If any non-invasive debug features exist, their behavior in Debug state is broadly the same as when<br />

non-invasive debug is not permitted. For details see About non-invasive debug authentication on page C7-2.<br />

Note<br />

When the DBGDSCR.DBGack bit, Force Debug Acknowledge, is set to 1 <strong>and</strong> the processor is in Non-debug<br />

state, the behavior of non-invasive debug features is IMPLEMENTATION DEFINED. However, in this case<br />

non-invasive debug features must behave either as if in Debug state or as if Non-debug state.<br />
