Both enable inputs are internally anded, one can be permanently activated, apart from this point it's a usual 8-bit interface.
 

when i use the glcd library in mikroc,i get some errors.
Unresolved extern GLCD_CS1
Unresolved extern GLCD_CS2
this is because i am not declaring these pins.as my glcd do not has these pins.so what should i have to do to resolve the errors.
 

On some graphic LCDs the enables are for different regions of the display. I suspect the two enables on that device are for the top and bottom halves of the pixel map so they need to be driven according to the position of the pixel you are addressing. You need to connect both back to the PIC and allocate pins for them to connect to.
GLCD_CS1 is the same as E1 and GLCD_CS2 is the same as E2.

Thanks.
It means
CS1 same as EN1
CS2 same as EN2
then what is EN in GLCD library
and what is A0 in my lcd?
i think it is RS pin.right?
 

I know that dual CS for segmented memory is pretty standard for graphic LCD. But there's no indication that this graphics controller uses it.

Generally GLCD drivers are very hardware dependent. The mikroC is said to work for KS108/KS107 controller, it most likely won't work for this chip without serious rework.
