Notes to
(1) All I/O pins have an option to enable weak pull-up except configuration, test, and JTAG pin. Weak pull-down feature is only available for JTAG
(2) Pin pull-up resistance values may be lower if an external source drives the pin higher than V

Schmitt Trigger Input
Cyclone III devices support Schmitt trigger input on TDI, TMS, TCK, nSTATUS,
nCONFIG, nCE, CONF_DONE, and DCLK pins. A Schmitt trigger feature introduces
hysteresis to the input signal for improved noise immunity, especially for signal with
slow edge rate.
