For all registers described in this subsection refer to the Fig.\ref{cts_logic}
\begin{description}
-\item[RW registers] of the trigger logic
- \begin{description}
\item [0xA0CC] Individual bits are enabling inputs
\item [0xA0D1 - 0xA0D4] Delay input signals, each nibble corresponds to one input e.g. 0xA0D1(3 to 0) corresponds to first input of the start part (Start 0). Delay value = 4 bit value * clock period (5ns)
\item [0xA0CD - 0xA0CE] Downscale input signals, each input signal is downscaled - $2^{value}$
\item [0xA0DC bit 6] Force update Shower pedestals trigger (write ..1..0)
\item [0xA0DC bit 7] Disable Shower pedestals update (generated once during each spill off)
\item [0xA0DC 11 down to 8] Select frequency for internally generated trigger - $781.25kHz/(2^value)$
- \end{description}
-\item[R registers] of the trigger logic
- \begin{description}
\item [0xA089] Trigger logic debug out
\item [0xA09B -0xA0BA] Scalers out
