Detailed Description

The definition of the RAW Data Header is specified in https://docs.google.com/document/d/1IxCCa1ZRpI3J9j3KCmw2htcOLIRVVdEcO-DDPcLNFM0 Every 8kB readout page starts with the RDH.

Note: the definition requires little endian architecture, for the moment we assume that this is the only type the software has to support (based on experience with previous systems) The definition of the RAW Data Header is specified in https://docs.google.com/document/d/1IxCCa1ZRpI3J9j3KCmw2htcOLIRVVdEcO-DDPcLNFM0 Every 8kB readout page starts with the RDH.
