PS Configuration
PS Configuration
You can use an Altera configuration device, a download cable, or an
intelligent host, such as a MAX^® II device or microprocessor to configure
a Cyclone II device with the PS scheme. In the PS scheme, an external host
(configuration device, MAX II device, embedded processor, or host PC)
controls configuration. Configuration data is input to the target
Cyclone II devices via the DATA0 pin at each rising edge of DCLK.

The Cyclone II decompression feature is fully available when
configuring your Cyclone II device using PS mode.
Table 13–6 shows the MSEL pin settings when using the PS configuration
scheme.

Single Device 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 II device.
Configuration data can be stored in RBF, HEX, or TTF format. Figure 13–9
shows the configuration interface connections between the Cyclone II
device and a MAX II device for single device configuration.
