Passive Parallel Asynchronous Configuration
All devices start and complete configuration at the same time.
Figure 7–32 shows multi-device PPA configuration when both devices are
receiving the same configuration data.

Notes to Figure 7–32:
(1) If not used, the CS pin can be connected to V_CC directly. If not used, the nCS pin can be connected to GND directly.
(2) The pull-up resistor should be connected to a supply that provides an acceptable input signal for all devices in the
chain. V_CC should be high enough to meet the V_IH specification of the I/O on the device and the external host.
(3) The nCEO pins of both devices are left unconnected when configuring the same configuration data into multiple
devices.

You can use a single configuration chain to configure Stratix II or
Stratix II GX devices with other Altera devices that support PPA
configuration, such as Stratix, Mercury^™, APEX^™ 20K, ACEX^® 1K, and
FLEX^® 10KE devices. To ensure that all devices in the chain complete
configuration at the same time or that an error flagged by one device
initiates reconfiguration in all devices, all of the device CONF_DONE and
nSTATUS pins must be tied together.
For more information on configuring multiple Altera devices in the same
configuration chain, refer to the Configuring Mixed Altera FPGA Chains
chapter in volume 2 of the Configuration Handbook.
