      Bcc     Label         conditional branch,depends on condition
      BRA     Label         unconditional branch(similar to JMP)
      BSR     Label         branch to subprogram.Return address is
                            deposited on stack,RTS causes return to that
                            address.

                            CHK instruction exception.
      DBcc    Reg,Label     check condition,decrement and branch
      JMP     Label         jump to address(similar to BRA)
      JSR     Label         jump to subroutine.Return address is
                            deposited on stack,RTS causes return to that
                            address.
