specifies the bit position to saturate to, in the range 0 to 15.
is the register holding the operand.
Halfword-wise unsigned saturation to any bit position.
USAT16 instruction saturates
each signed halfword 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 on either halfword, this instruction
sets the Q flag. To read the state of the Q flag, use an
The 32-bit instruction is available in A32 and T32.
For the Armv7‑M architecture, the 32-bit T32 instruction is only available in an Arm®v7E-M implementation.
There is no 16-bit version of this instruction in T32.
