Only system programmers can use the supervisor programming model to implement
operating system functions, I/O control, and memory management subsystems. This
supervisor/user distinction in the M68000 family architecture allows for the writing of
application software that executes in the user mode and migrates to the MC68040 from
any M68000 family platform without modification. The supervisor programming model
contains the control features that system designers need to modify system software when
porting to a new design. For example, only the supervisor software can read or write to
the transparent translation registers of the MC68040. The existence of the transparent
translation registers does not affect the programming resources of user application
programs.
