Open-Drain Output
Stratix II GX devices provide an optional open-drain (equivalent to an
open collector) output for each I/O pin. This open-drain output enables
the device to provide system-level control signals (for example, interrupt
and write enable signals) that can be asserted by any of several devices.
Bus Hold
Each Stratix II GX device I/O pin provides an optional bus-hold feature.
The bus-hold circuitry can hold the signal on an I/O pin at its last-driven
state. Since the bus-hold feature holds the last-driven state of the pin until
the next input signal is present, an external pull-up or pull-down resistor
is not needed to hold a signal level when the bus is tri-stated.
