3.2 Intrinsic functions
ANSI cannot directly access some Cortex-M3 instructions. This section describes intrinsic functions 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:
Table 3.2. CMSIS intrinsic functions to generate some Cortex-M3 instructions
Instruction
CMSIS intrinsic function
CPSIE I
void __enable_irq(void)
CPSID I
void __disable_irq(void)
CPSIE F
void __enable_fault_irq(void)
CPSID F
void
__disable_fault_irq(void)
ISB
void __ISB(void)
DSB
void __DSB(void)
DMB
void __DMB(void)
REV
uint32_t __REV(uint32_t int
value)
REV16
uint32_t __REV16(uint32_t int
value)
REVSH
uint32_t __REVSH(uint32_t int
value)
RBIT
uint32_t __RBIT(uint32_t int
value)
SEV
void __SEV(void)
WFE
void __WFE(void)
WFI
void __WFI(void)
The CMSIS also provides a number of functions for accessing the special registers using MRS and MSR
instructions:
