Cyclone II Device Handbook, Volume 1
Open-Drain Output
Cyclone 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 (that is, interrupt and
write-enable signals) that can be asserted by any of several devices.
