access peripheral registers
define exception vectors
the names of:
the registers of the core peripherals
the core exception vectors
a device-independent interface for RTOS kernels, including a debug channel.
The CMSIS includes address definitions and data structures for the core peripherals in the Cortex-M3
processor. It also includes optional interfaces for middleware components comprising a TCP/IP stack
and a Flash file system.
CMSIS simplifies software development by enabling the reuse of template code and the combination
of CMSIS-compliant software components from various middleware vendors. Software vendors can
expand the CMSIS to include their peripheral definitions and access functions for those peripherals.
This document includes the register names defined by the CMSIS, and gives short descriptions of the
CMSIS functions that address the processor core and the core peripherals.
Note
This document uses the register short names defined by the CMSIS. In a few cases these
differ from the architectural short names that might be used in other documents.
The following sections give more information about the CMSIS:
2.2 Memory model
This section describes the processor memory map, the behavior of memory accesses, and the bit-
banding features. The processor has a fixed memory map that provides up to 4GB of addressable
memory. The memory map is:
