MOV (inverted wide immediate)
Move (inverted wide immediate) moves an inverted 16-bit immediate value to a register.
This is an alias of MOVN. This means:
- The encodings in this description are named to match the encodings of MOVN.
- The description of MOVN gives the operational pseudocode for this instruction.

32-bit (sf == 0 && hw == 0x)
is equivalent to
MOVN <Wd>, #<imm16>, LSL #<shift>
and is the preferred disassembly when ! (IsZero(imm16) && hw != '00') && ! IsOnes(imm16).
64-bit (sf == 1)
is equivalent to
MOVN <Xd>, #<imm16>, LSL #<shift>
and is the preferred disassembly when ! (IsZero(imm16) && hw != '00').
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. |
Operation
The description of MOVN gives the operational pseudocode for this instruction.
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.
