CODE： R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 L L L H 列地址（0～63） 功能： DD RAM 的列地址存储在Y地址计数器中，读写数据对列地址有影响，在对DD RAM进行读写操作后，Y地址自动加一。 5、状态检测
CODE： R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 H L BF L ON/OFF RST L L L L 功能：读忙信号标志位(BF)、复位标志位(RST)以及显示状态位(ON/OFF)。 BF=H：内部正在执行操作； BF=L：空闲状态。 RST=H：正处于复位初始化状态； RST=L：正常状态。 ON/OFF=H：表示显示关闭； ON/OFF=L：表示显示开。 6、写显示数据
CODE： R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 L H D7 D6 D5 D4 D3 D2 D1 D0 功能：写数据到DD RAM，DD RAM是存储图形显示数据的，写指令执行后Y地址计数器自动加1。D7-D0位数据为1表示显示，数据为0表示不显示。写数据到DD RAM前，要先执行“设置页地址”及“设置列地址”命令。 7、读显示数据

功能：从DD RAM读数据，读指令执行后Y地址计数器自动加1。从DD RAM读数据前要先执行“设置页地址” 及“设置列地址”命令。 六、接口时序 １.写操作时序
