LF: Supervisor Stack
The RAM.TXT file that comes with FARGO mentions a "Supervisor
Stack." Upon browsing the 68k programmers guide, I could not determine
where, or what, the switch from the user's stack to the supervisor stack
takes place. Could anyone shed some light on this for me. Also, other
than exceptions and TRAP's, does the processor ever enter the supervisor
state. How? Other than the ability to execute privileged instructions,
and the setting of the supervisor flag in SR, does the change to
supervisor state change anything else.
THANX.
