◆ __RESTRICT
| #define __RESTRICT __restrict |
◆ __NOP
| #define __NOP | ( | ) |
No Operation.
No Operation does nothing. This instruction can be used for code alignment purposes.
◆ __WFI
| #define __WFI | ( | ) |
Wait For Interrupt.
Wait For Interrupt is a hint instruction that suspends execution until one of a number of events occurs.
◆ __WFE
| #define __WFE | ( | ) |
Wait For Event.
Wait For Event is a hint instruction that permits the processor to enter a low-power state until one of a number of events occurs.
◆ __SEV
| #define __SEV | ( | ) |
Send Event.
Send Event is a hint instruction. It causes an event to be signaled to the CPU.
◆ __ISB
| #define __ISB | ( | ) |
Instruction Synchronization Barrier.
Instruction Synchronization Barrier flushes the pipeline in the processor, so that all instructions following the ISB are fetched from cache or memory, after the instruction has been completed.
◆ __DSB
| #define __DSB | ( | ) |
Data Synchronization Barrier.
Acts as a special kind of Data Memory Barrier. It completes when all explicit memory accesses before this instruction complete.
◆ __DMB
| #define __DMB | ( | ) |
Data Memory Barrier.
Ensures the apparent order of the explicit memory operations before and after the instruction, without ensuring their completion.
◆ __REV
| #define __REV | ( | value | ) | value |
Reverse byte order (32 bit)
Reverses the byte order in unsigned integer value. For example, 0x12345678 becomes 0x78563412.
- Parameters
-
[in] value Value to reverse
- Returns
- Reversed value
◆ __REV16
| #define __REV16 | ( | value | ) | value |
Reverse byte order (16 bit)
Reverses the byte order within each halfword of a word. For example, 0x12345678 becomes 0x34127856.
- Parameters
-
[in] value Value to reverse
- Returns
- Reversed value
◆ __REVSH
| #define __REVSH | ( | value | ) | value |
Reverse byte order (16 bit)
Reverses the byte order in a 16-bit value and returns the signed 16-bit result. For example, 0x0080 becomes 0x8000.
- Parameters
-
[in] value Value to reverse
- Returns
- Reversed value
◆ __ROR
| #define __ROR | ( | ) |
Rotate Right in unsigned value (32 bit)
Rotate Right (immediate) provides the value of the contents of a register rotated by a variable number of bits.
- Parameters
-
[in] op1 Value to rotate [in] op2 Number of Bits to rotate
- Returns
- Rotated value
◆ __BKPT
| #define __BKPT | ( | value | ) | value |
Breakpoint.
Causes the processor to enter Debug state. Debug tools can use this to investigate system state when the instruction at a particular address is reached.
- Parameters
-
[in] value is ignored by the processor. If required, a debugger can use it to store additional information about the breakpoint.
◆ __RBIT
| #define __RBIT | ( | ) | _byteswap_ulong(_rotr(value, 16)) |
Reverse bit order of value.
Reverses the bit order of the given value.
- Parameters
-

- Returns
- Reversed value
