Before stack traces will function, a special unwind macro called UNWIND
must be used.  The following unwind macros are predefined within SAT:

     $1 ($0) nmsat > macl 
     macro unwind
     macro uwlock1
     macro uwlock2
     macro uwlock3
     macro uwlock4
     macro uwlock5
     macro uwlockup

Executing the macro UNWIND restores the environment to a state in which
stack tracing can be performed.  UNWIND needs to be done only when
looking at the state of the machine at the time of the failure.  (It is
not necessary when switching to other pins with the PIN command.)  The
remainder of the macros listed above support the UNWIND macro.  Do not
use the other macros.

     $2 ($0) nmsat > unwind 
     $3 ($0) nmsat >

At this point, most of the System Debug commands are available to analyze
the failure.  If there is still the need to take a dump, the EXIT command
is used to return control to ISL where the DUMP utility may be invoked.
