 +===== State machine changes =====
 +  - ''​Clear separation of acquisition and data transfer'':​ The firmware is not controlling the acquisition time, it just throws a BUSY when one TDC fifo is ALmost Full (25 over 32). The BUSYs are collected by the MDCC board that terminates the acquisition window when one busy is seen and do not restart a window until all BUSYs are low.
 +  - ''​Data transmit per channel'':​ Once the acquisition window is end, a BUSY is set per FEB until the data transfer is completed. It consists first to an Event packet containing the GTC (window count) and the Absolute BCID (readout time 200 ns steps). Then TDCs are scanned one by one , if not empty a channel packet is sent. Once all TDCs are browsed, BUSY is released and the FEB is in IDLE for the next window.
