MCF5407 Integrated ColdFire¨ Microprocessor
Programming Model, Addressing Modes, and Instruction Set
￥
User modeWhen the processor is in user mode (SR[S] = 0), only a subset of the registers can be
accessed and privileged instructions cannot be executed. Typically, most application processing
occurs in user mode. Entry into user mode is usually accomplished by executing a return from
exception instruction (RTE) (assuming the value of SR[S] saved on the stack is 0) or a MOVE, SR
instruction (assuming SR[S] is 0).
Supervisor modeSupervisor mode protects system resources from uncontrolled access by users.
In supervisor mode, complete access to all registers and the entire ColdFire instruction set is
provided. Typically, system programmers use the supervisor programming model to implement
operating system functions and provide I/O control. The supervisor programming model provides
access to the same registers as the user model, plus additional registers for conTguring on-chip
system resources, as described in Section 1.4.3, òSupervisor Registers.ó
Exceptions (including interrupts) are handled in supervisor mode.
