Though it is possible to use MOV as a branch instruction, ARM strongly recommends the use of
a BX or BLX instruction to branch for software portability to the ARM instruction set.
If S is specified, these instructions:
• bit[0] of the value written to the PC is ignored
• a branch occurs to the address created by forcing bit[0] of that value to 0.
• update the N and Z flags according to the result
• can update the C flag during the calculation of Operand2, see
• do not affect the V flag.

; Write value of 0x000B to R11, flags get updated
; Write value of 0xFA05 to R1, flags are not updated
; Write value in R12 to R10, flags get updated
; Write value of 23 to R3
; Write value of stack pointer to R8
; Write value of 0xFFFFFFF0 (bitwise inverse of 0xF)
; to the R2 and update flags
