使用V850 於 MiniCube2 ,需要預留中斷 (uart mode)

        -- Securing a reception interrupt vector for serial communication
                .section "INTUA0R"
                .space 4, 0xff
        -- Securing a reception interrupt vector for serial communication
                .section "INTUA0T"
                .space 4, 0xff
