ORP Bypass and Fast Output Multiplexers

The ORP bypass and fast-path output multiplexer is a 4:1 multiplexer and allows the 5-PT fast path to bypass the

ORP and be connected directly to the pin with either the regular output or the inverted output. This multiplexer also

Output Enable Routing Multiplexers

The OE Routing Pool provides the corresponding local output enable (OE) product term to the I/O cell.

I/O Cell

The I/O cell contains the following programmable elements: output buffer, input buffer, OE multiplexer and bus

maintenance circuitry. Figure 8 details the I/O cell.
