Symbol
The beginning of this waveform shows the device in user-mode. In user-mode, nCONFIG, nSTATUS, and
CONF_DONE are at logic high levels. When nCONFIG is pulled low, a reconfiguration cycle begins.
Upon power-up, the Stratix II device holds nSTATUS low for the time of the POR delay.
Upon power-up, before and during configuration, CONF_DONE is low.
DCLK should not be left floating after configuration. It should be driven high or low, whichever is convenient.
DATA[] is available as user I/Os after configuration and the state of these pins depends on the dual-purpose pin
settings.
