multi-device configuration. Once the first AT17A Series
device finishes sending configuration data, it drives its
nCASC pin low, which drives the nCS pin of the second
AT17A Series device low. This activates the second AT17A
Series device to send configuration data to the FPGA
device.
The first AT17A Series device clocks all subsequent AT17A
Series devices until configuration is complete. Once all
configuration data is transferred and nCS on the first

AT17A Series device is driven high by CONF_DONE on
the FPGA devices, the first AT17A Series device clocks 16
additional cycles to initialize the FPGA device. Then the
first AT17A Series device goes into zero-power (idle) state.
If nCS on the first AT17A Series device is driven high
before all configuration data is transferred–or if the nCS is
not driven high after all configuration data is transferred–
the nSTATUS is driven low, indicating a configuration error.
