You can also use PPA mode to configure multiple Stratix and Stratix GX
devices. Multi-device PPA configuration is similar to single-device PPA
configuration, except that the Stratix and Stratix GX devices are cascaded.
After you configure the first Stratix or Stratix GX device, nCEO is asserted,
which asserts the nCE pin on the second device, initiating configuration.
Because the second Stratix or Stratix GX device begins configuration
within one write cycle of the first device, the transfer of data destinations
is transparent to the microprocessor. All Stratix and Stratix GX device
CONF_DONE pins are tied together; therefore, all devices initialize and
enter user mode at the same time. See
