CFAG320240C-FMI-T initialization problem

I'm using CFAG320240C-FMI-T with ADuC842, In text screen everything is fine but I have problems on graphics screen. Graphics appear shifted and I couldn't manage to display any graphics right. Here's my initialization code:

Code:
writeControl(0x40);     // SYSTEM SET
writeData(0x30);			
writeData(0x87);	// FX
writeData(0x07);	// FY
writeData(0x27);	// C/R
writeData(0x42);	// TC/R
writeData(0xEF);	// LF
writeData(0x28);	// APL
writeData(0x00);	// APH

writeControl(0x44);     // SCROLL
writeData(0x00);
writeData(0x00);
writeData(0xEF);	// 240 - 1
writeData(0xB0);
writeData(0x04);
writeData(0xEF);	// 240 - 1
writeData(0x00);	
writeData(0x00);	
writeData(0x00);	
writeData(0x00);	

writeControl(0x5A);    // HDOT_SCR
writeData(0x00);

writeControl(0x5B);    // OVLAY
writeData(0x00);	

writeControl(0x58);    // DISP OFF
writeData(0x00);

writeControl(0x5D);    // CSR FORM
writeData(0x04);
writeData(0x86);

writeControl(0x4C);    // CSRDIR RIGHT

writeControl(0x59);    // DISP ON
writeData(0x16);
And I'm using code below for the Graphics:

Code:
writeControl(0x46);   // CSRW    
writeData(0xB0);
writeData(0x04);

writeControl(0x42);   // MWRITE
writeData(First_EightPixels);
writeData(2nd_EightPixels);
writeData(3rd_EightPixels);
writeData(4th_EightPixels);
...
...
Pixels don't appear on the left-top (0,0) location. I think I have problems on defining SCROLL. Any help greatly appriciated. Epson Data sheet is quite complicated and badly written.

PS for CF Techs: Any application note for this display would be good!!!
