LSR (immediate) Logical shift right (immediate) This instruction shifts a register value right by an immediate number of bits, shifting in zeros, and writes the result to the destination register. If PSTATE.DIT is 1: The execution time of this instruction is independent of: The values of the data supplied in any of its registers. The values of the NZCV flags. The response of this instruction to asynchronous exceptions does not vary based on: The values of the data supplied in any of its registers. The values of the NZCV flags.
