● 忙标志:BF    BF标志提供内部工作情况.BF=1表示模块在进行内部操作,此时模块不接受外部指令和数据.BF=0时,模块为准备状态,随时可接受外部指令和数据.     利用STATUS RD 指令,可以将BF读到DB7总线,从而检验模块之工作状态.●  字型产生ROM（CGROM）    字型产生ROM（CGROM）提供8192个此触发器是用于模块屏幕显示开和关的控制。DFF=1为开显示（DISPLAY ON),DDRAM 的内容就显示在屏幕上，DFF=0为关显示（DISPLAY OFF)。    DFF 的状态是指令DISPLAY ON/OFF和RST信号控制的。●   显示数据RAM（DDRAM）模块内部显示数据RAM提供64×2个位元组的空间，最多可控制4行16字（64个字）的中文字型显示，当写入显示数据RAM时，可分别显示CGROM与CGRAM的字型；此模块可显示三种字型，分别是半角英数字型(16*8)、CGRAM字型及CGROM的中文字型，三种字型的选择，由在DDRAM中写入的编码选择，在0000H—0006H的编码中（其代码分别是0000、0002、0004、0006共4个）将选择CGRAM的自定义字型，02H—7FH的编码中将选择半角英数字的字型，至于A1以上的编码将自动的结合下一个位元组，组成两个位元组的编码形成中文字型的编码BIG5（A140—D75F），GB（A1A0-F7FFH）。   ●  字型产生RAM(CGRAM)    字型产生RAM提供图象定义(造字)功能, 可以提供四组16×16点的自定义图象空间，使用者可以将内部字型没有提供的图象字型自行定义到CGRAM中，便可和CGROM中的定义一样地通过DDRAM显示在屏幕中。●  地址计数器AC地址计数器是用来贮存DDRAM/CGRAM之一的地址,它可由设定指令暂存器来改变，之后只要读取或是写入DDRAM/CGRAM的值时，地址计数器的值就会自动加一，当RS为“0”时而R/W为“1”时，地址计数器的值会被读取到DB6——DB0中。

●      光标/闪烁控制电路


    此模块提供硬体光标及闪烁控制电路，由地址计数器的值来指定DDRAM中的光标或闪烁位置。

备注;当IC1在接受指令前,微处理器必须先确认其内部处于非忙碌状态,即读取BF标志时,BF需为零,方可接受新的指令;如果在送出一个指令前并不检查BF标志,那么在前一个指令和这个指令中间必须延长一段较长的时间,即是等待前一个指令确实执行完成。


应用举例：


1 、使用前的准备


   先给模块加上工作电压，再按照下图的连接方法调节LCD的对比度，使其显示出黑色的底影。


   此过程亦可以初步检测LCD有无缺段现象。


2、字符显示


带中文字库的128X64-0402B每屏可显示4行8列共32个16×16点阵的汉字，每个显示RAM可显示1个中


　


文字符或2个16×8点阵全高ASCII码字符，即每屏最多可实现32个中文字符或64个ASCII码字符的显示。带中文字库的128X64-0402B内部提供128×2字节的字符显示RAM缓冲区（DDRAM）。字符显示是通过将字符显示编码写入该字符显示RAM实现的。根据写入内容的不同，可分别在液晶屏上显示CGROM（中文字库）、HCGROM（ASCII码字库）及CGRAM（自定义字形）的内容。三种不同字符/字型的选择编码范围为：0000～0006H（其代码分别是0000、0002、0004、0006共4个）显示自定义字型，02H～7FH显示半宽ASCII码字符，A1A0H～F7FFH显示8192种GB2312中文字库字形。字符显示RAM在液晶模块中的地址80H～9FH。字符显示的RAM的地址与32个字符显示区域有着一一对应的关系，其对应关系如下表所示。

3 、图形显示  


先设垂直地址再设水平地址(连续写入两个字节的资料来完成垂直与水平的坐标地址)


垂直地址范围 AC5...AC0


水平地址范围 AC3…AC0


绘图RAM 的地址计数器（AC）只会对水平地址(X 轴)自动加一,当水平地址=0FH 时会重新设为00H 但并不会对垂直地址做进位自动加一，故当连续写入多笔资料时，程序需自行判断垂直地址是否需重新设定。GDRAM的坐标地址与资料排列顺序如下图：


　


3、应用说明


用带中文字库的128X64显示模块时应注意以下几点：


①欲在某一个位置显示中文字符时，应先设定显示字符位置，即先设定显示地址，再写入中文字符编码。


②显示ASCII字符过程与显示中文字符过程相同。不过在显示连续字符时，只须设定一次显示地址，由模块自动对地址加1指向下一个字符位置，否则，显示的字符中将会有一个空ASCII字符位置。


③当字符编码为2字节时，应先写入高位字节，再写入低位字节。


④模块在接收指令前，向处理器必须先确认模块内部处于非忙状态，即读取BF标志时BF需为“0”，方可接受新的指令。如果在送出一个指令前不检查BF标志，则在前一个指令和这个指令中间必须延迟一段较长的时间，即等待前一个指令确定执行完成。指令执行的时间请参考指令表中的指令执行时间说明。⑤“RE”为基本指令集与扩充指令集的选择控制位。当变更“RE”后，以后的指令集将维持在最后的状态，除非再次变更“RE”位，否则使用相同指令集时，无需每次均重设“RE”位。
