MOV (inverted wide immediate)

Move inverted wide immediate value

This instruction moves an inverted 16-bit immediate value to a register.

Encoding: Immediate packed into 16-bit value and 2-bit shift

32-bit (sf == 0 && hw == 0x)

MOV <Wd>, #<imm>

Equivalent to: MOVN <Wd>, #<imm16>, LSL #<shift>

64-bit (sf == 1)

MOV <Xd>, #<imm>

Equivalent to: MOVN <Xd>, #<imm16>, LSL #<shift>

Explanations

<Wd>: Is the 32-bit name of the general-purpose destination register, encoded in the "Rd" field.
<imm>: For the "32-bit" variant: is a 32-bit immediate, the bitwise inverse of which can be encoded in "imm16:hw", but excluding 0xFFFF0000 and 0x0000FFFF
<imm>: For the "64-bit" variant: is a 64-bit immediate, the bitwise inverse of which can be encoded in "imm16:hw".
<Xd>: Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field.

Operational Notes

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.
