Notes to
(1) All I/O pins have an option to enable weak pull-up except configuration, test, and JTAG pins.
(2) Pin pull-up resistance values may be lower if an external source drives the pin higher than V
(3) The internal weak pull-down feature is only available for the JTAG TCK pin. The typical value for this internal weak pull-down resistor is
(4) These specifications are valid with ±10% tolerances to cover changes over PVT.

Schmitt Trigger Input
Stratix IV devices support Schmitt trigger input on the 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 signals with
slow edge rates.
