PCI-Clamp Diode
Cyclone IV Device Handbook, Volume 1
Cyclone IV devices provide an optional PCI-clamp diode enabled input and output
for each I/O pin. Dual-purpose configuration pins support the diode in user mode if
the specific pins are not used as configuration pins for the selected configuration
scheme. For example, if you are using the active serial (AS) configuration scheme, you
cannot use the clamp diode on the ASDO and nCSO pins in user mode. Dedicated
configuration pins do not support the on-chip diode.
The PCI-clamp diode is available for the following I/O standards:

If the input I/O standard is one of the listed standards, the PCI-clamp diode is
enabled by default in the Quartus II software.
