Sticky saturation flag
WebThe result of the operation is saturated to the largest possible positive or negative number. If the result would have overflowed and has been saturated, the overflow flag (CPSR Q bit) is set. This flag is said to be sticky. When set it will remain set until explicitly cleared by … WebThe Q flag is a cumulative (sticky) saturation bit in the APSR (Application Program Status Register) indicating that an operation saturated, or in some cases, overflowed. It is set …
