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.

(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 the DATA[0]pin high or low, whichever is more

When using the AS configuration scheme, DCLK is a Cyclone IV device output pin and must not be driven externally.
