I/O pin has an individual slew-rate control, allowing you to specify the
slew rate on a pin-by-pin basis. The slew-rate control affects both the
rising and falling edges.
Bus Hold
Each Stratix device I/O pin provides an optional bus-hold feature. The
bus-hold circuitry can weakly hold the signal on an I/O pin at its last-
driven state. Since the bus-hold feature holds the last-driven state of the
pin until the next input signal is present, an external pull-up or pull-down
resistor is not needed to hold a signal level when the bus is tri-stated.
Table 2–29
The bus-hold circuitry also pulls undriven pins away from the input
threshold voltage where noise can cause unintended high-frequency
switching. You can select this feature individually for each I/O pin. The
bus-hold output drives no higher than V
signals. If the bus-hold feature is enabled, the programmable pull-up
option cannot be used. Disable the bus-hold feature when using open-
drain outputs with the GTL+ I/O standard or when the I/O pin has been
configured for differential signals.
The bus-hold circuitry uses a resistor with a nominal resistance (R
approximately 7 kΩ to weakly pull the signal level to the last-driven state.
See the DC & Switching Characteristics chapter of the Stratix Device
Handbook, Volume 1 for the specific sustaining current driven through this
resistor and overdrive current used to identify the next-driven input
level. This information is provided for each V
The bus-hold circuitry is active only after configuration. When going into
user mode, the bus-hold circuit captures the value on the pin present at
the end of configuration.
