control to reduce system noise and signal overshoot.
possible settings for the I/O standards with drive strength control.
Open-Drain Output
Cyclone 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.

Table 2–11. Programmable Drive Strength
SSTL-3 class I and II, SSTL-2 class I and II, and 3.3-V PCI I/O Standards do not
support programmable drive strength.
This is the default current strength setting in the Quartus II software.
