PIC子程序。本程序实现液晶显示控制器SED1335的初始化。

入口参数：图形显示区的行数在SOU中（前0~240行）。

出口参数：无。

占用资源：W,STATUS,RB0~RB2,RC,023H,024H,028H,029H,二重堆栈。

说 明：1.显示屏为320*240点阵。

2.显示屏前128行为图形方式，后112行为文本方式

3.SAD1=0000H,SAD2=5000H,SAD3=3000H所有的区都开显示且不闪烁。

4.AP=48,显示缓冲区将被清0-PIC subroutine. Implementation of this program SED1335 LCD controller initialization.　 Entry parameters: number of lines in graphics display area in the SOU (the former 0 ~ 240 line).　 Output Parameters: None.　 Take up resources: W, STATUS, RB0 ~ RB2, RC, 023H, 024H, 028H, 029H, double stack.　 Note: 1. 320* 240 dot matrix display.　 2. 128 actions before the graphical display, text mode behavior after 112　3.SAD1 = 0000H, SAD2 = 5000H, SAD3 = 3000H display all the areas were open and not blinking.　 4.AP = 48, display buffer will be clear 0
