is an optional shift. It must be one of the following:
is in the range 1-32 (A32) or 1-31 (T32).
is 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 operand.
You can use SP in A32 instructions but this is deprecated. You cannot use SP in T32 instructions.
If saturation occurs, this instruction sets the Q flag. To
read the state of the Q flag, use an
This instruction is available in A32 and T32.
There is no 16-bit version of this instruction in T32.
