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) Do not leave DCLK floating after configuration. It must be driven high or low, whichever is more convenient.
(5) DATA[7..0] is available as user I/O pin after configuration; the state of the pin depends on the dual-purpose pin
