Example
R11, #0x000B

R10, R12
R3, #23
R8, SP
R2, #0xF
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.
