Arithmetic Operation Instructions
Operation
Rn + Rm → Rn
Rn + imm → Rn
Rn + Rm + T → Rn,
carry → T
Rn + Rm → Rn,
overflow → T
When R0 = imm, 1 → T
Otherwise, 0 → T
When Rn = Rm, 1 → T
Otherwise, 0 → T
When Rn ≥ Rm (unsigned),
1 → T
Otherwise, 0 → T
When Rn ≥ Rm (signed),
1 → T
Otherwise, 0 → T
When Rn > Rm (unsigned),
1 → T
Otherwise, 0 → T
When Rn > Rm (signed),
1 → T
Otherwise, 0 → T
When Rn ≥ 0, 1 → T
Otherwise, 0 → T
When Rn > 0, 1 → T
Otherwise, 0 → T
Operation
T → Rn
Rm → swap lower 2 bytes
→ Rn
Rm → swap upper/lower
words → Rn
