Add
Dreg_hi = Dreg_hi + Dreg_hi (S)
Subtract
Dreg_hi = Dreg_lo – Dreg_lo (NS)
Subtract
Dreg_hi = Dreg_lo – Dreg_lo (S)
Subtract
Dreg_hi = Dreg_lo – Dreg_hi (NS)
Subtract
Dreg_hi = Dreg_lo – Dreg_hi (S)
Subtract
Dreg_hi = Dreg_hi – Dreg_lo (NS)
Subtract
Dreg_hi = Dreg_hi – Dreg_lo (S)
Subtract
Dreg_hi = Dreg_hi – Dreg_hi (NS)
Subtract
Dreg_hi = Dreg_hi – Dreg_hi (S)
Add/Subtract-Prescale Up
Dreg_hi = Dreg + Dreg (RND12)
Add/Subtract-Prescale Up
Dreg_hi = Dreg – Dreg (RND12)
Add/Subtract-Prescale Down
Dreg_hi = Dreg + Dreg (RND20)
Add/Subtract-Prescale Down
Dreg_hi = Dreg – Dreg (RND20)
Move Register Half
A0.H = Dreg_hi
Move Register Half
A1.H = Dreg_hi
Modify-Increment
Dreg_hi = (A0 += A1)
