25.4.2 Intrinsic functions
Table 363. Cortex-M0 instructions
ISO/IEC C code cannot directly access some Cortex-M0 instructions. This section
describes intrinsic functions that can generate these instructions, provided by the CMSIS
and that might be provided by a C compiler. If a C compiler does not support an
appropriate intrinsic function, you might have to use inline assembler to access the
relevant instruction.
The CMSIS provides the following intrinsic functions to generate instructions that ISO/IEC
C code cannot directly access:
