SAT Saturate bit. Can be cleared only by the MVC instruction and can be set
only by a functional unit. The set by a functional unit has priority over a

bit will not be modified by a conditional instruction whose condition is false.
0 Any unit does not perform a saturate.
1 Any unit performs a saturate.
