The pin’s datain signals can drive the logic array. The logic array drives
the control and data signals, providing a flexible routing resource. The
row or column IOE clocks, io_clk[5..0], provide a dedicated routing
resource for low-skew, high-speed clocks. The global clock network
generates the IOE clocks that feed the row or column I/O regions (see
“Global Clock Network & Phase-Locked Loops” on page

Each IOE contains its own control signal selection for the following
