    9.3.8 Relative
    Relative addressing is only for branch instructions. If the branch
    condition is true, the CPU finds the effective branch destination by
    adding the signed byte following the opcode to the contents of the
    program counter. If the branch condition is not true, the CPU goes to the
    next instruction. The offset is a signed, two’s complement byte that gives
    a branching range of –128 to +127 bytes from the address of the next
    location after the branch instruction.
    When using the Freescale assembler, the programmer does not need to
    calculate the offset, because the assembler determines the proper offset
    and verifies that it is within the span of the branch.
    9.4 Instruction Types
    The MCU instructions fall into five categories:
    Register/memory instructions
    Read-modify-write instructions
    Jump/branch instructions
    Bit manipulation instructions
    Control instructions
