PM0214 The Cortex-M4 processor
261
The CMSIS includes address definitions and data structures for the core peripherals in the
Cortex-M4 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 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:
• Section 2.5.4: Power management programming hints on page 49
• CMSIS intrinsic functions on page 58
• Interrupt set-enable register x (NVIC_ISERx) on page 210
• NVIC programming hints on page 218
