THIS MANUAL IS INCOMPLETE but what is written here should be more accurate and up to date than the old "functional specification". Please e-mail me if you find mistakes/omissions here (Eric H).

The TTS state is sent over the same 5.0Gb/s link as the DAQ data. There's an input port in our link logic on the AMC side:

-- TTS port
    TTSclk            : in  std_logic;  -- clock source which clocks TTS signals
    TTS               : in  std_logic_vector (3 downto 0);

When the TTS state changes, a control word is sent across the link to transfer the information with minimum latency to the AMC13. The final TTS output state is simply a priority encoding of the 12 AMC states plus the local AM13 one.

TTC Simulator

The AMC13 has the ability to generate simulated TTC signals and distribute them to AMC cards in the crate.
