You can perform PS configuration on Cyclone III devices with an external
intelligent host, such as a MAX II device, microprocessor with flash
memory, or a download cable. In the PS scheme, an external host controls
configuration. Configuration data is clocked into the target Cyclone III
device via the DATA[0] pin at each rising edge of DCLK.

configuration scheme with different configuration voltage standards.
If your system already contains a common flash interface (CFI) flash
memory, you can utilize it for the Cyclone III device configuration storage
as well. The MAX II PFL feature provides an efficient method to program
CFI flash memory devices through the JTAG interface and the logic to
control configuration from the flash memory device to the Cyclone III
device. Both PS and FPP configuration schemes are supported using this
PFL feature.
For more information about PFL, refer to the AN 386: Using the MAX II
Parallel Flash Loader with the Quartus II Software application note on the
Altera website at www.altera.com.
PS Configuration Using a MAX II Device as an External Host
In the PS configuration scheme, you can use a MAX II device as an
intelligent host that controls the transfer of configuration data from a
storage device, such as flash memory, to the target Cyclone III device. You
