10.10 Intrinsic functions
78
SAM3S Preliminary
Table 10-13. Cortex-M3 instructions (Continued)
ANSI cannot directly access some Cortex-M3 instructions. This section describes intrinsic func-
tions that can generate these instructions, provided by the CMIS 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 some instructions.
The CMSIS provides the following intrinsic functions to generate instructions that ANSI cannot
directly access:
