RS7 - Deinterleaver Enable
1: The input flow is deinterleaved.
0: The input flow is not affected.
RS6 - Synchro Enable
1: The synchro is processed.
0: The synchro word search is disabled. The bit-to-byte conversion

RS5 - Reed-Solomon Enable
1: The input code is corrected.
0: No correction happens, all the data is fed to the descrambler.
RS4 - Descrambler Enable
1: The output flow from Reed-Solomon decoder is descrambled.
0: The descrambler is disactivated.
RS3 - Write Error Bit
1: If an uncorrectible error happens in DVB, the MSB of the first byte
0: The output flow is unchanged.
RS2 - Block Synchro
1: The first byte of each packet is forced to Hex 47 in mode A.
0: The first byte is the one that is received. In DVB, it should be the
RS1 - Output Clock Polarity
