After power-up, the Stratix IV device goes through a POR. The POR delay depends on
the PORSEL pin setting. When PORSEL is driven low, the standard POR time is

all user I/O pins. After the device successfully exits POR, all user I/O pins continue to
be tri-stated. If nIO_pullup is driven low during power up and configuration, the user
I/O pins and dual-purpose I/O pins have weak pull-up resistors, which are on (after
POR) before and during configuration. If nIO_pullup is driven high, the weak pull-up
resistors are disabled.
The configuration cycle consists of three stages: reset, configuration, and initialization.
While nCONFIG or nSTATUS are low, the device is in the reset stage. To initiate
configuration, the MAX II device must drive the nCONFIG pin from low to high.
To begin the configuration process, you must fully power V

levels.
When nCONFIG goes high, the device comes out of reset and releases the open-drain
nSTATUS pin, which is then pulled high by an external 10-kΩ pull-up resistor. After
nSTATUS is released, the device is ready to receive configuration data and the
configuration stage begins. When nSTATUS is pulled high, the MAX II device places
the configuration data one byte at a time on the DATA[7..0] pins.
Stratix IV devices receive configuration data on the DATA[7..0] pins and the clock is
received on the DCLK pin. Data is latched into the device on the rising edge of DCLK. If
you are using the Stratix IV decompression and/or design security features,
configuration data is latched on the rising edge of every fourth DCLK cycle. After the
configuration data is latched in, it is processed during the following three DCLK cycles.
Therefore, you can only stop DCLK after three clock cycles after the last data is latched
into the Stratix IV devices.
Data is continuously clocked into the target device until CONF_DONE goes high. The
CONF_DONE pin goes high one byte early in FPP modes. The last byte is required for
FPP mode. After the device has received the next-to-last byte of the configuration data
successfully, it releases the open-drain CONF_DONE pin, which is pulled high by an
external 10-kΩ pull-up resistor. A low-to-high transition on CONF_DONE indicates
configuration is complete and initialization of the device can begin. The CONF_DONE
pin must have an external 10-kΩ pull-up resistor for the device to initialize.
In Stratix IV devices, the initialization clock source is either the internal oscillator or
the optional CLKUSR pin. By default, the internal oscillator is the clock source for
initialization. If you use the internal oscillator, the Stratix IV device provides itself
with enough clock cycles for proper initialization. Therefore, if the internal oscillator
is the initialization clock source, sending the entire configuration file to the device is
sufficient to configure and initialize the device. Driving DCLK to the device after
configuration is complete does not affect device operation.
