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
allows the register output to bypass the ORP to achieve faster t
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.
