2 The Cortex-M3 Processor
2.1 Programmers model
This section describes the Cortex-M3 programmers model. In addition to the individual core register
descriptions, it contains information about the processor modes and privilege levels for software
execution and stacks.
2.1.1 Processor mode and privilege levels for software execution
The processor modes are:
Thread mode
Used to execute application software. The processor enters Thread mode when it
comes out of reset.
Handler mode
Used to handle exceptions. The processor returns to Thread mode when it has
finished exception processing.
The privilege levels for software execution are:
Unprivileged
The software:
has limited access to the MSR and MRS instructions, and cannot use the CPS
instruction
cannot access the system timer, NVIC, or system control block
might have restricted access to memory or peripherals.
Unprivileged software executes at the unprivileged level.
Privileged
The software can use all the instructions and has access to all resources.
Privileged software executes at the privileged level.
In Thread mode, the CONTROL register controls whether software execution is privileged or
unprivileged, see Section 2.1.3.7 (p. 12) . In Handler mode, software execution is always privileged.
Only privileged software can write to the CONTROL register to change the privilege level for software
execution in Thread mode. Unprivileged software can use the SVC instruction to make a supervisor call
to transfer control to privileged software.
2.1.2 Stacks
The processor uses a full descending stack. This means the stack pointer indicates the last stacked item
on the stack memory. When the processor pushes a new item onto the stack, it decrements the stack
pointer and then writes the item to the new memory location. The processor implements two stacks, the
main stack and the process stack, with independent copies of the stack pointer, see Section 2.1.3.2 (p.
In Thread mode, the CONTROL register controls whether the processor uses the main stack or the
process stack, see Section 2.1.3.7 (p. 12) . In Handler mode, the processor always uses the main
stack. The options for processor operations are:
