Mnemomic
Saturate fractional value in data register to fit in high portion
If Da > $007FFFFFFF then $007FFF0000
If Da < $FF80000000 then $FF80000000
Else Da & $FFFFFF0000
Saturate value in data register to fit in 32 bits
If Da > $007FFFFFFF then $007FFF0000
If Da < $FF80000000 then $FF80000000
Else Dn
Subtract long with carry
Db – Da – C
Subtract and round
Rnd(Dn – Da)
