Passive Serial Configuration
Figure 10–13. PS Configuration Timing Waveform
Notes to
(1) The beginning of this waveform shows the device in user mode. In user mode, nCONFIG, nSTATUS, and CONF_DONE are at logic high levels.
(2) After power-up, the Stratix IV device holds nSTATUS low for the time of the POR delay.
(3) After power-up, before and during configuration, CONF_DONE is low.
(4) Do not leave DCLK floating after configuration. You can drive it high or low, whichever is more convenient.
(5) DATA[0] is available as a user I/O pin after configuration. The state of this pin depends on the dual-purpose pin settings.
