Operation
Rn + Rm → Rn
Rn + imm → Rn
Rn + Rm + T → Rn,
Carry → T
Rn + Rm → Rn,
Overflow → T
If R0 = imm, 1 → T
If Rn = Rm, 1 → T
If Rn ≥ Rm with
unsigned data, 1 → T
If Rn ≥ Rm with signed
data, 1 → T
If Rn > Rm with
unsigned data, 1 → T
If Rn > Rm with signed
data, 1 → T
If Rn > 0, 1 → T
If Rn ≥ 0, 1 → T
If Rn and Rm have
an equivalent byte,
1→T
Single-step division
(Rn/Rm)
MSB of Rn → Q, MSB
of Rm → M, M ^ Q → T
0 → M/Q/T
