decoder controls the device’s nCS and CS pins. This decoder allows the
microprocessor to select the Stratix or Stratix GX device by accessing a
particular address, simplifying the configuration process.
The device’s nCS or CS pins can be toggled during PPA configuration if

the nCS and CS signals. You can tie one of the nCS or CS signals to its
active state (i.e., nCS may be tied low) and toggle the other signal to
control configuration.
Stratix and Stratix GX devices can serialize data internally without the
microprocessor. When the Stratix or Stratix GX device is ready for the
next byte of configuration data, it drives RDYnBSY high. If the
microprocessor senses a high signal when it polls RDYnBSY, the
microprocessor strobes the next byte of configuration data into the
device. Alternatively, the nRS signal can be strobed, causing the
RDYnBSY signal to appear on DATA7. Because RDYnBSY does not need to
