Board Configuration
2.1.6 Output Connectors
The outputs from the FPGA are not labeled for LSB and MSB. This is because
of the capability of the ADS527x data converters to switch between MSB first
or LSB first for the output data. This configuration is accessed in the internal
registers of the ADS527x through a serial interface. Refer to the respective
ADS527x datasheet and the ADS527xEVM for more details. If the standard
configuration for the data converter is used, then the following diagram can be
used for capturing the data.
