/******************************************************************************
* 文件名稱：ili932x.c
* 摘 要：支持ILI9320和ILI9325驅動IC控制的QVGA顯示屏，使用16位并行傳輸
到頭文件中配置 屏幕使用方向和驅動IC類型
注意：16位數據線色彩分布>> BGR(565)
* 當前版本：V1.3
* 修改說明：版本修訂說明：
1.修改翻轉模式下的ASCII字符寫Bug
2.增加可以在翻轉模式下的自動行寫
3.優化刷圖片 使用流水線方法提效率
*重要說明！
在.h文件中，#define Immediately時是立即顯示當前畫面
而如果#define Delay，則只有在執行了LCD_WR_REG(0x0007,0x0173);
之后才會顯示，執行一次LCD_WR_REG(0x0007,0x0173)后，所有寫入數
據都立即顯示。
#define Delay一般用在開機畫面的顯示，防止顯示出全屏圖像的刷新
過程
