MOVZ
Move wide with zero moves an optionally-shifted 16-bit immediate value to a register.
This instruction is used by the alias MOV (wide immediate).

Assembler Symbols
<Wd> |
Is the 32-bit name of the general-purpose destination register, encoded in the "Rd" field. |
<Xd> |
Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field. |
<imm> |
Is the 16-bit unsigned immediate, in the range 0 to 65535, encoded in the "imm16" field. |
Alias Conditions

Operational information
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.
