Description
Indicates that the corresponding EmbeddedICE-RT
watchpoint register has matched the conditions
currently present on the address, data, and control
buses. This signal is independent of the state of the
watchpoint enable control bit.
Represents the debug request signal that is presented
to the core debug logic. This is a combination of
EDBGRQ and bit 1 of the debug control register.
An external debugger can force the processor into
debug state by asserting this signal.
