Register Descriptions
This section lists and describes the Cortex-M3 registers, in the order shown in Figure 2-3 on page 58.
The core registers are not memory mapped and are accessed by register name rather than offset.
Note: The register type shown in the register descriptions refers to type during program execution
in Thread mode and Handler mode. Debug access can differ.
