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.
