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