Description

• MOV{S}: Move
• MVN: Move NOT.

Syntax

MOV{S}{cond} Rd, Operand2
MOV{cond} Rd, #imm16
MVN{S}{cond} Rd, Operand2

where:

S

Is an optional suffix. If S is specified, the condition code flags are updated on the result of the operation:

• update the N and Z flags according to the result
• can update the C flag during the calculation of Operand2
• do not affect the V flag.

cond

Is an optional condition code, see Conditional execution.

Rd

Specifies the destination register.

Operand2

Is a flexible second operand. See Flexible second operand for details of the options.

imm16

This is any value in the range 0-65535.

Examples

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.
