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.
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:
• Power management programming hints on page 2-34
• CMSIS functions on page 3-9
• Accessing the Cortex-M4 NVIC registers using CMSIS on page 4-4
• NVIC programming hints on page 4-9.
