| The ARM Cortex Microcontroller Software Interface Standard (CMSIS) defines a |
| set of standard interfaces to ARM Cortex-M 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. |
