Moving/copying an integer value from a register into another register

---

• The mov instruction - again
  • The mov instruction can also be used to move/copy an integer (= 32 bits) value from one register to another register

  • The assembler syntax to move the value stored in a register rM to a register rN (any register in the ARM processor) is:

    mov rN, rM

    The entire register rM will by copied into the register rN

    Examples:

    mov r0, r4 // Copies r4 into r0 mov r1, r9 // Copies r9 into r1
