Figure 17: 3-State Buffers Implement a Multiplexer. The selection is accomplished by the buffer 3-state signal.
Figure 15: Programmable Interconnection of Longlines. This is provided at the edges of the routing area.
Three-state buffers allow the use of horizontal Longlines to form on-chip wired AND and multiplexed buses. The left two
non-clock vertical Longlines per column (except XC3020A) and the outer perimeter Longlines may be programmed as
connectable half-length lines.
Figure 16: 3-State Buffers Implement a Wired-AND Function. When all the buffer 3-state lines are High, (high
impedance), the pull-up resistor(s) provide the High output. The buffer inputs are driven by the control signals or a Low.
