Input
Output control signal from the Stratix IV device to the serial
configuration device in AS mode that enables the
configuration device.
In AS mode, nCSO has an internal pull-up resistor that is
always active.
In PS and FPP configurations, DCLK is the clock input used
to clock data from an external source into the target device.
Data is latched into the device on the rising edge of DCLK.
In AS mode, DCLK is an output from the Stratix IV device
that provides timing for the configuration interface. In AS
mode, DCLK has an internal pull-up resistor (typically
25 kΩ) that is always active.
In AS configuration schemes, this pin is driven into an
inactive state after configuration completes. You can use
this pin as a user I/O during user mode.
In PS or FPP schemes that use a control host, you must
drive DCLK either high or low, whichever is more
convenient. In passive schemes, you cannot use DCLK as a
user I/O during user mode.
Toggling this pin after configuration does not affect the
configured device.
Data input. In serial configuration modes, bit-wide
configuration data is presented to the target device on the
DATA0 pin.
In AS mode, DATA0 has an internal pull-up resistor that is
always active.
After PS or FPP configuration, DATA0 is available as a user
I/O pin. The state of this pin depends on the Dual-Purpose
Pin settings.
Data inputs. Byte-wide configuration data is presented to
the target device on DATA[7..0].
In serial configuration schemes, they function as user I/O
pins during configuration, which means they are tri-stated.
After FPP configuration, DATA[7..1] are available as user
I/O pins. The state of these pins depends on the
Dual-Purpose Pin settings.
