LSL: logical shift left LSR: logical shift right ASL: arithmetic shift ARM Instruction Set - Shift & Rotate The contents of Rm are used directly as the second operand. A logical shift right (LSR) is similar, but the contents of Rm are moved to less significant. ARM has two logical shift operations, namely LSL (Logical Shift Left) and LSR (Logical Shift Right). LSL is a logical shift left by 0 to 31 places. The vacated MOV is the basic instruction that moves the constant data in the register or move that data from one register to another. In the Thumb instruction set MOVTThe ARM instruction LSRS{ cond } pc, Rm ,# sh always disassembles to the preferred form MOVS{ cond } pc, Rm {,shift} . Caution. Do not use the S suffix when Basic Types of ARM Instructions This is equivalent to r0=r1+r2 and set the LSR – logical shift by n bits – unsigned division by 2n. ARM instructions that use Rs must not use r15. Thumb instructions must not use r15 or r13. Condition flags. We will learn ARM assembly programming at the. l l d it i l t Instruction set defines the operations that can MOV R0, R2, LSR #2 @ R0:=R2>>2.
