User manual
34.2.7.1.3 Restrictions
34.2.7.1.4 Condition flags
34.2.7.1.5 Examples
If the returned result is different from the value to be saturated, it is called saturation. If
saturation occurs, the instruction sets the Q flag to 1 in the APSR. Otherwise, it leaves the
Q flag unchanged. To clear the Q flag to 0, you must use the MSR instruction, see
Section
To read the state of the Q flag, use the MRS instruction, see
Do not use SP and do not use PC.
These instructions do not affect the condition code flags.
If saturation occurs, these instructions set the Q flag to 1.
•
otherwise, the result returned is the same as the value to be saturated.
