Operand Syntax
Operation
Source + destination → destination
Source + destination → destination
Immediate data + destination → destination
Immediate data + destination → destination
Source + destination + X → destination
Source & destination → destination
Immediate data & destination → destination
X/C ← (Dx << Dy) ← 0
X/C ← (Dx << #<data>) ← 0
MSB → (Dx >> Dy) → X/C
MSB → (Dx >> #<data>) → X/C
If condition true, then PC + 2 + d
~(<bit number> of destination) → Z,
Bit of destination
~(<bit number> of destination) → Z;
0 → bit of destination
PC + 2 + d → PC
n
~(<bit number> of destination) → Z;
1→ bit of destination
SP – 4 → SP; next sequential PC→ (SP); PC + 2 + d
~(<bit number> of destination) → Z
0 → destination
Destination – source
→ PC
