Use the CBZ or CBNZ instructions to avoid changing the condition code flags and to reduce the
number of instructions.
CBZ Rn, label does not change condition flags but is otherwise equivalent to:
CBNZ Rn, label does not change condition flags but is otherwise equivalent to:
The restrictions are:
These instructions do not change the flags.
• Rn must be in the range of R0 to R7
• the branch destination must be within 4 to 130 bytes after the instruction
• these instructions must not be used inside an IT block.
