update the N and Z flags according to the result
can update the C flag during the calculation of Operand2, see Section 3.3.3 (p. 38)
do not affect the V flag.
3.5.6.5 Example
MOVS
R11, #0x000B
; Write value of 0x000B to R11, flags get updated
MOV
R1, #0xFA05
; Write value of 0xFA05 to R1, flags are not updated
MOVS
R10, R12
; Write value in R12 to R10, flags get updated
MOV
R3, #23
; Write value of 23 to R3
MOV
R8, SP
; Write value of stack pointer to R8
MVNS
R2, #0xF
; Write value of 0xFFFFFFF0 (bitwise inverse of 0xF)
; to the R2 and update flags
3.5.7 MOVT
Move Top.
3.5.7.1 Syntax
MOVT{cond} Rd, #imm16
where:
cond
is an optional condition code, see Section 3.3.7 (p. 43) .
Rd
is the destination register.
imm16
is a 16#bit immediate constant.
3.5.7.2 Operation
MOVT
writes a 16#bit immediate value, imm16, to the top halfword, Rd[31:16], of its destination register.
The write does not affect Rd[15:0].
The MOV, MOVT instruction pair enables you to generate any 32#bit constant.
3.5.7.3 Restrictions
Rd
must not be SP and must not be PC.
3.5.7.4 Condition flags
This instruction does not change the flags.
3.5.7.5 Examples
MOVT
R3, #0xF123 ; Write 0xF123 to upper halfword of R3, lower halfword
; and APSR are unchanged
3.5.8 REV, REV16, REVSH, and RBIT
Reverse bytes and Reverse bits.
3.5.8.1 Syntax
op{cond} Rd, Rn
