- The ARM Cortex Microcontroller Software Interface Standard (CMSIS) defines a
- set of standard interfaces to ARM Cortex family SOCs. In particular, the
- CMSIS-CORE component standardizes the software interface to core and peripheral
- registers, as well as exception names and the system clock frequency. Multiple
- SOC vendors, including NXP and Nordic Semiconductor, include the CMSIS-CORE
- header files in their SOC header files. These SOC header files are in turn used
- by the vendor's peripheral drivers.
