1 & \multicolumn{3}{X|}{``Central'' - For a normal central FPGA design with Cts and/or GbE}\\
& 3 -- 0 & ExtModule & Type of external trigger module (0: none, 1: CBM MBS, 2: Mainz M2)\\
- & 7 -- 4 & CtsTdc & Number of TDC channels included. Usually connected to the first trigger inputs of the CTS.
+ & 4 & CtsTdc & TDC channels included. Usually connected to the first trigger inputs of the CTS.
If a trigger module is present, the first channel will connect to its async output signal \\
- & 8 & CtsTdcX & The connection of TDC channels is non-standard. Refer to documentation. \\
+ & 5 & CtsTdcX & The connection of TDC channels is non-standard. Refer to documentation. \\
+ & 11 -- 8 & DoubleEdge & See table 2.\\
