strength control.
Open-Drain Output
Stratix II 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 (e.g., interrupt and write-
enable signals) that can be asserted by any of several devices.
Bus Hold
Each Stratix II device I/O pin provides an optional bus-hold feature. The
bus-hold circuitry can weakly 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, you do not need an external
pull-up or pull-down resistor to hold a signal level when the bus is
tri-stated.
