The diagram presents electrical connectivity. The diagram locations do not necessarily match the physical location on the device,
although the coordinate locations shown are correct.
Number of DCMs and locations of these DCM varies for different device densities. The left and right DCMs are only in the
XC3S1200E and XC3S1600E. The XC3S100E has only two DCMs, one on the top right and one on the bottom right of the die.
