34.2.7 Saturating instructions
This section describes the saturating instructions, SSAT and USAT.
Signed Saturate and Unsigned Saturate to any bit position, with optional shift before
saturating.
op{cond} Rd, #n, Rm {, shift #s}
where:
op is one of:
cond is an optional condition code, see
Rd is the destination register.
n specifies the bit position to saturate to:
Rm is the register containing the value to saturate.
shift #s is an optional shift applied to Rm before saturating. It must be one of the following:
These instructions saturate to a signed or unsigned n-bit value.
The SSAT instruction applies the specified shift, then saturates to the signed range
−2
The USAT instruction applies the specified shift, then saturates to the unsigned range
0 ≤ x ≤ 2
For signed n-bit saturation using SSAT, this means that:
For unsigned n-bit saturation using USAT, this means that:

SSAT Saturates a signed value to a signed range.
USAT Saturates a signed value to an unsigned range.
ASR #s: where s is in the range 1 to 31
LSL #s: where s is in the range 0 to 31.
n–1
n ranges from 1 to 32 for SSAT.
n ranges from 0 to 31 for USAT.
if the value to be saturated is less than −2
if the value to be saturated is greater than 2
otherwise, the result returned is the same as the value to be saturated.
if the value to be saturated is less than 0, the result returned is 0
if the value to be saturated is greater than 2
