PM0214 Rev 9 91/262
PM0214 The STM32 Cortex-M4 instruction set
261
3.5.7 MOVT
Move Top.
Syntax
MOVT{cond} Rd, #imm16
Where:
• ‘cond’ is an optional condition code (see Conditional execution on page 65).
• ‘Rd’ is the destination register.
• ‘imm16’ is a 16-bit immediate constant.
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.
Restrictions
Rd must be neither SP nor PC.
Condition flags
This instruction does not change the flags.
Examples
MOVT R3, #0xF123 ; write 0xF123 to upper halfword of R3,
; lower halfword and APSR are unchanged
