 * @brief   Creats video trigger, time-stamp/sync clock and rest signal (for ETIS)
 *
 * This module generates the Video trigger signal for the Camera at the choosen fps. It also generates the time-stamp/sync clock that is
 * used by both Acquision (ETIS) and Compression (Lip6) boards for time-stamp counters along with a start signal whic resets the time-stamp
 * counters when the acquisition start command comes from PC (Acacia). The value of time-stamp register is transmitted to the Video coder via AvalonST source
