When multiple devices in Cyclone III device family are cascaded, you can selectively
enable the compression feature for each device in the chain.
of two devices in Cyclone III device family. The first device has compression enabled
and receives compressed bitstream from the configuration device. The second device
has the compression feature disabled and receives uncompressed data. You can
generate programming files for this setup from the Convert Programming Files
dialog box from the File menu in the Quartus II software.

The following section describes power-on-reset (POR) for Cyclone III device family.
POR Circuit
The POR circuit keeps the device in the reset state until the power supply voltage
levels have stabilized after device power-up. After device power-up, the device does
not release nSTATUS until the required voltages listed in table
are above the POR trip point of the device. V

In Cyclone III device family, you can select either a fast POR time or standard POR
time depending on the MSEL pin settings. The fast POR time is 3 ms < TPOR < 9 ms
for the fast configuration time. The standard POR time is 50 ms < TPOR < 200 ms,
which has a lower power-ramp rate.
