The assertion and negation of the freeze signal when in debug mode disable is controlled by the exception
cause register (ECR) and the debug enable register (DER) as described in
the freeze signal the software needs to program the relevant bits in the debug enable register (DER). In
order to negate the freeze line the software needs to read the exception cause register (ECR) in order to
clear it and perform an rfi instruction.
If the exception cause register (ECR) is not cleared before the rfi is performed the freeze signal is not
negated. Therefore it is possible to nest inside a software monitor debugger without affecting the value of
the freeze line although rfi may be performed a few times. Only before the last rfi the software needs to
clear the exception cause register (ECR).
The above mechanism enables the software to accurately control the assertion and the negation of the
freeze signal.
