/** Global variables of the LFR flight software.
 *
 * @file
 * @author P. LEROY
 *
 * Among global variables, there are:
 * - RTEMS names and id.
 * - APB configuration registers.
 * - waveforms global buffers, used by the waveform picker hardware module to store data.
 * - spectral  matrices buffesr, used by the hardware module to store data.
 * - variable related to LFR modes parameters.
 * - the global HK packet buffer.
 * - the global dump parameter buffer.
