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 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 in the Stratix II 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.
Programmable Pull-Up Resistor
Each Stratix II device I/O pin provides an optional programmable
pull-up resistor during user mode. If you enable this feature for an I/O
pin, the pull-up resistor (typically 25 kΩ) weakly holds the output to the
V
Programmable pull-up resistors are only supported on user I/O pins, and
are not supported on dedicated configuration pins, JTAG pins or
dedicated clock pins.
