is an optional shift. It must be one of the following:
nis in the range 1-32 (ARM) or 1-31 (Thumb).
nis in the range 0-31.
USAT instruction applies the specified shift to a signed value, then
saturates to the unsigned range 0 ≤ x ≤ 2sat - 1.
You cannot use PC for any register.
You can use SP in ARM instructions but this is deprecated in ARMv6T2 and above. You cannot use SP in Thumb instructions.
If saturation occurs, this instruction sets the Q flag. To
read the state of the Q flag, use an
This ARM instruction is available in ARMv6 and above.
This 32-bit Thumb instruction is available in ARMv6T2 and above.
There is no 16-bit version of this instruction in Thumb.
