Note to
(1) The write clock comes from the PLL.
IOE registers are expanded to allow source-synchronous systems to have faster
register-to-register transfers and resynchronization. For Arria II GX devices, both top,
bottom, and right IOEs have the same capability. Right IOEs have extra features to
support LVDS data transfer. For Arria II GZ devices, both top and bottom, and left
and right IOEs have the same capability. Left and right IOEs have extra features to
support LVDS data transfer.
