AO40 emergency software restart routine

Just curious here.
Let's assume there's no hardware failure involved but that the command 
processing system is just locked up so it's unable to process real-time 
commands and carry out satellite house keeping. Is the command-assist 
software separate from the rest of the system and immune from lockups? One 
would think that command-assist would also be a casualty of the lock up and 
that a locked up system would be unable or unaware that it should load and 
run the software. How do command-assist and other recovery routines 
actually work?

Also, what sort of commands was AO40 processing when the telemetry stopped?

KB7ADL with fingers crossed.
