LEVEL7 Non-Maskable Interrupt Debugger

LEVEL7, the non-maskable interrupt debugger, is a utility to examine the status of a locked-up system.

This can be very useful when debugging interrupt level routines or other functions which may appear to

lock the system. You can also set LEVEL7 to trigger on the standard exception vectors.

To use LEVEL7 to debug a “locked” system, you need to emulate a power fail condition by using either

a switch wired to the UPS port on the CPU board, or via front panel control on those systems supporting

that function. Therefore, you can use LEVEL7 to diagnose system lockups only on CPU boards which

have a UPS port, such as the AM-185-50, AM-4000, Eagle 550, and AM-6000, or on CPU boards which

have configurable front panel control of LEVEL7, such as the Eagle 450 and AM-6060. Information on

constructing the necessary switch for invoking LEVEL7, or information on configuring the CPU board

for front panel control of LEVEL7 is at the end of this document.

Using the LEVEL7 debugger preempts any power fail operations usually performed within the

AMOS monitor; therefore it should only be installed during debugging, not as a normal system

utility.

If your CPU does not have a UPS port or front panel LEVEL7 control, you can still use LEVEL7

to debug any condition which causes one of the normal exception vectors by using the /E or /T

switch, described below.

LEVEL7 is user-extensible via custom overlays, several of which are included. Further information on

programming these overlays is covered later in this document. If you develop your own overlay, and

want it to be included, please submit it with source and instructions to Alpha Microsystems. The overlay

will become property of Alpha Microsystems if included with LEVEL7; no compensation will be given

to the author.
