The problem is this: When reading FSMC value always returns the previous value written in the FSMC.
And you need a color value of the pixel SSD1963 ...
Actually, what's the catch ???

reads as:
#define LCD_REG      (*((volatile unsigned short *) 0x60000000))
#define LCD_RAM      (*((volatile unsigned short *) 0x60020000))

//0x2E read_memory_start
LCD_Write_Com(0x2E);
rtk[0]=LCD_RAM; //All values rtk [] are the same, i.e., that has been recorded last time (LCD_Write_Com (0x2E))
rtk[1]=LCD_RAM;
rtk[2]=LCD_RAM;
rtk[3]=LCD_RAM;
