PS Configuration Timing
A PS configuration must meet the setup and hold timing parameters and the
maximum clock frequency. When using a microprocessor or another intelligent host
to control the PS interface, ensure that you meet these timing requirements.

Notes to
(1) The beginning of this waveform shows the device in user mode. In user mode, nCONFIG, nSTATUS, and
(2) After power-up, the Cyclone III device family holds nSTATUS low during POR delay.
(3) After power-up, before and during configuration, CONF_DONE is low.
(4) In user mode, drive DCLK either high or low when using the PS configuration scheme, whichever is more convenient.
(5) Do not leave the DATA[0] pin floating after configuration. Drive it high or low, whichever is more convenient.
Table 9–13
CONF_DONE are at logic-high levels. When nCONFIG is pulled low, a reconfiguration cycle begins.
When using the AS configuration scheme, DCLK is a Cyclone III device family output pin and must not be driven
externally.
