2.1.6. The Cortex Microcontroller Software Interface Standard

For a Cortex-M7 microcontroller system, the Cortex Microcontroller Software Interface Standard (CMSIS) defines:

The CMSIS includes address definitions and data structures for the core peripherals in the Cortex-M7 processor.

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 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:
