想学习液晶显示，请问下面这个代码和数字是什么意思啊？

if(DeviceCode==0x9320||DeviceCode==0x9300)
{
  LCD_WriteReg(0x00,0x0000);
  LCD_WriteReg(0x01,0x0100); //Driver Output Contral.
  LCD_WriteReg(0x02,0x0700); //LCD Driver Waveform Contral.
  LCD_WriteReg(0x03,0x1030);//Entry Mode Set.
  //LCD_WriteReg(0x03,0x1018); //Entry Mode Set.

  LCD_WriteReg(0x04,0x0000); //Scalling Contral.
  LCD_WriteReg(0x08,0x0202); //Display Contral 2.(0x0207)
  LCD_WriteReg(0x09,0x0000); //Display Contral 3.(0x0000)
  LCD_WriteReg(0x0a,0x0000); //Frame Cycle Contal.(0x0000)
  LCD_WriteReg(0x0c,(1<<0)); //Extern Display Interface Contral 1.(0x0000)
  LCD_WriteReg(0x0d,0x0000); //Frame Maker Position.
  LCD_WriteReg(0x0f,0x0000); //Extern Display Interface Contral 2.     
  delay_ms(50);
  LCD_WriteReg(0x07,0x0101); //Display Contral.
  delay_ms(50);           
  LCD_WriteReg(0x10,(1<<12)|(0<<8)|(1<<7)|(1<<6)|(0<<4)); //Power Control 1.(0x16b0)
  LCD_WriteReg(0x11,0x0007);        //Power Control 2.(0x0001)
  LCD_WriteReg(0x12,(1<<8)|(1<<4)|(0<<0));    //Power Control 3.(0x0138)
  LCD_WriteReg(0x13,0x0b00);        //Power Control 4.
  LCD_WriteReg(0x29,0x0000);        //Power Control 7.

  LCD_WriteReg(0x2b,(1<<14)|(1<<4));     
  LCD_WriteReg(0x50,0); //Set X Star
  //水平GRAM终止位置Set X End.
  LCD_WriteReg(0x51,239); //Set Y Star
  LCD_WriteReg(0x52,0); //Set Y End.t.
  LCD_WriteReg(0x53,319); //

  LCD_WriteReg(0x60,0x2700); //Driver Output Control.
  LCD_WriteReg(0x61,0x0001); //Driver Output Control.
  LCD_WriteReg(0x6a,0x0000); //Vertical Srcoll Control.

  LCD_WriteReg(0x80,0x0000); //Display Position? Partial Display 1.
  LCD_WriteReg(0x81,0x0000); //RAM Address Start? Partial Display 1.
  LCD_WriteReg(0x82,0x0000); //RAM Address End-Partial Display 1.
  LCD_WriteReg(0x83,0x0000); //Displsy Position? Partial Display 2.
  LCD_WriteReg(0x84,0x0000); //RAM Address Start? Partial Display 2.
  LCD_WriteReg(0x85,0x0000); //RAM Address End? Partial Display 2.

  LCD_WriteReg(0x90,(0<<7)|(16<<0)); //Frame Cycle Contral.(0x0013)
  LCD_WriteReg(0x92,0x0000); //Panel Interface Contral 2.(0x0000)
  LCD_WriteReg(0x93,0x0001); //Panel Interface Contral 3.
  LCD_WriteReg(0x95,0x0110); //Frame Cycle Contral.(0x0110)
  LCD_WriteReg(0x97,(0<<8)); //
  LCD_WriteReg(0x98,0x0000); //Frame Cycle Contral.   
  LCD_WriteReg(0x07,0x0173); //(0x0173)
原子老师，我想问下，液晶这块我该咋学习呢，象我粘贴的代码，扩内的数字什么意思啊，为什么要这么设置呢啊
