Operation
If DC = 1, MACL → Dz
If DC = 0, MACL → Dz
Dz → MACH
If DC = 1, Dz → MACH
If DC = 0, Dz → MACH
Dz → MACL
If DC = 1, Dz → MACL
If DC = 0, Dz → MACL
Sx + Sy + DC → Dz
Carry → DC
Sx – Sy – DC → Dz
Borrow → DC
Sx – Sy → DC update*
If Sx < 0, 0 – Sx → Dz
If Sx > = 0, nop
If Sy < 0, 0 – Sy → Dz
If Sx > = 0, nop
Sx + h'00008000 → Dz
LSW of Dz → h'0000
Sy + h'00008000 → Dz
LSW of Dz → h'0000
