MOVSI – Move and Shift According to an Immediate Shift
Value
Syntax:
movsi operand, ab, #signed 5-bit immediate
Operation:
The operand is sign-extended to 36 bits.
If 0 < #immediate ≤ 15, then operand << #immediate –> ab
If -16 ≤ #immediate < 0, then operand >> - #immediate –> ab
If #immediate = 0, then operand –> ab.
Operand:
rN
y
rb
