[Micro2440] CON6 and CON4

hi,

what is the conector CON6 and CON4 in Micro2440 nand 256 ?

Thanks in advance.

i have found on pdf micro2440 in chinese version

CON6 is GPIO and CON4 is for CMOS.

You can use CON4 too for IO, if you dont need camera.  I am using usb
camera so I am using this CON4 as IO.

thanks
