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.

Send Event is a hint instruction. It causes an event to be signaled to the CPU.

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.

This function acts as a special kind of Data Memory Barrier. It completes when all explicit memory accesses before this instruction complete.

This function ensures the apparent order of the explicit memory operations before and after the instruction, without ensuring their completion.

This function reverses the byte order in integer value.

Parameters:
[in]valueValue to reverse
Returns:
Reversed value

This function reverses the byte order in two unsigned short values.

Parameters:
[in]valueValue to reverse
Returns:
Reversed value

This function reverses the byte order in a signed short value with sign extension to integer.

Parameters:
[in]valueValue to reverse
Returns:
Reversed value

This function Rotate Right (immediate) provides the value of the contents of a register rotated by a variable number of bits.

Parameters:
[in]valueValue to rotate
[in]valueNumber of Bits to rotate
Returns:
Rotated value
