• Advantech AMT-73, AMT-70/AMT-73/AMT-75 Installation and Operation In some cases, where the uncoded block size does not exactly line up on a byte-boundary, a number of padding bits are inserted after the CRC. They are set to zero. Once the CRC is inserted, the uncoded data is then always scrambled. This does not add or remove data from the stream, merely exclusive-ORs it with a pseudo-random binary sequence that can be removed in the decoder. 9.2.2 Framing In or
