1 .Field of the Invention
The present invention relates to a micro-controller, and more particularly to an improved micro-controller to simplify the hardware necessary for accessing an extended memory.
2 .Description of the Prior Art
In order to adopt a micro-controller unit (MCU), for example, for use in a controller for a cassette or a floppy disk memory device, logic is embodied by the existence of wiring which increases the need for hardware according to the type of controller. When the controller includes an integrated processor that can program a micro program a control according to the use may be made simply by changing the micro program and in this circumstance, a micro-controller is needed.
Furthermore, when a read only memory(ROM) used to store a predetermined amount of the micro program is constructed on the semi-conductor chip of the micro controller unit, an exclusive pin controller for the chip can be created, and it is economical for this purpose, to choose a presently available one-chip micro-controller unit having a internal ROM. In this way, a standard application is available by using the above identified floppy disk device and the one-chip micro-controller unit incorporating a micro program.
When the micro-controller unit includes an internal ROM with a given capacity, there exists hardware that can access an extended memory so as to accommodate the possibility of external extended memory. Generally,
since the one-chip micro-controller unit has an extra external terminal pin, a control signal ,namely, a high or low level signal, can be applied to this pin so as to access and control an internal ROM or an external extended memory

1 .领域的发明
本发明涉及到一个微控制器,更具体地说,以改善微控制器,以简化硬件必要进入一个内存扩展.
2 .描述事先艺术
为了通过一项微控制器单元（ MCU ）的,例如使用于控制器的一盘或软盘的存储设备,逻辑,它表现为存在的布线,增加了必要的硬件按类型控制器.当控制器包括一个综合处理器,可程式微程序的控制,根据使用,可取得简单地通过改变微程序,并在此情况下,微控制器是需要的.
此外,当一个唯读记忆体（ ROM ）内,用来存放预定金额的微观计划是建于半导体芯片的微控制器单元,专访针控制器芯片,可以创造,它是为经济为此,要选择一个现有的单芯片微控制器单元具有内置ROM .就这样,一个标准的应用,可利用上述确定的软碟装置和一个片上微控制器单元包含一个微型计划.
当微控制器单元包括一个内置ROM与某一特定身份,不存在硬体可以存取内存扩展等,以容纳可能的外部内存扩展.一般来说,
由于单芯片微控制器单元有一个额外的外部码头边,一个控制信号,即高或低一级的信号,可以应用到这个引脚等,以获取和控制一个内部ROM或外部内存扩展
