Receive Data Channel Shift
In receive direction (DR), data of all IOM-2000 channels (ch0...7 if one VIP is used,
ch0 ... ch23 if three VIPs are used) is shifted by 2 channels with respect to the
transmitted data channels (DX), assuming a start of transmission of ch0 bit0 with the
FSC signal. DELIC is transmitting ch0, while receiving ch2 via DR the same time, etc.
