The UFM block communicates with the logic array similar to LAB-to-LAB interfaces.
The UFM block connects to row and column interconnects and has local interconnect
regions driven by row and column interconnects. This block also has DirectLink
interconnects for fast connections to and from a neighboring LAB. For more
information about the UFM interface to the logic array, see

Table 2–2
Each MAX II device has four dual-purpose dedicated clock pins (GCLK[3..0], two
pins on the left side and two pins on the right side) that drive the global clock network
for clocking, as shown in
purpose I/O if they are not used to drive the global clock network.
The four global clock lines in the global clock network drive throughout the entire
device. The global clock network can provide clocks for all resources within the
device including LEs, LAB local interconnect, IOEs, and the UFM block. The global
clock lines can also be used for global control signals, such as clock enables,
synchronous or asynchronous clears, presets, output enables, or protocol control
signals such as TRDY and IRDY for PCI. Internal logic can drive the global clock
network for internally-generated global clocks and control signals.
