This paper describes the TOTEM Trigger System Firmware that is operational at LHC since 2009. The TOTEM experiment is devoted to the forward hadronic physics at collision energy from 2.7 to 14TeV. It is composed of three different subdetectors that are placed at 9, 13.5, and 220m from the Interaction Point 5. A time-critical-logic firmware is implemented inside FPGA circuits to review collisions and to select the relevant ones to be stored by the Data Acquisition (DAQ). The Trigger system has been modified in the 2012-2013 LHC runs allowing the experiment to take data in cooperation with CMS.
