Modification effectuée dans fsw >= 3.1.0.1
Le compteur est correctement géré.
La valeur hk_lfr_ahb_correctable est ajoutée dans le compteur récapitulatif hk_lfr_le_cnt (criticité L pour les erreur ahb_correctable, d'après le document RPW-SYS-MEB-###-FMC-000207-LES_Issue3_Rev1_FDIR_Analysis)
Le compteur générale des erreur L est mis à jour dans la fonction:

void hk_lfr_le_me_he_update()

Dans la fonction:

void hk_lfr_le_me_he_update()

//update the low severity error counter
    hk_lfr_le_cnt =
            current_hk_lfr_le_cnt
            + housekeeping_packet.hk_lfr_dpu_spw_parity
            + housekeeping_packet.hk_lfr_dpu_spw_disconnect
            + housekeeping_packet.hk_lfr_dpu_spw_escape
            + housekeeping_packet.hk_lfr_dpu_spw_credit
            + housekeeping_packet.hk_lfr_dpu_spw_write_sync
            + housekeeping_packet.hk_lfr_timecode_erroneous
            + housekeeping_packet.hk_lfr_timecode_missing
            + housekeeping_packet.hk_lfr_timecode_invalid
            + housekeeping_packet.hk_lfr_time_timecode_it
            + housekeeping_packet.hk_lfr_time_not_synchro
            + housekeeping_packet.hk_lfr_time_timecode_ctr
            + housekeeping_packet.hk_lfr_ahb_correctable;

Puis:

// LE
    housekeeping_packet.hk_lfr_le_cnt[0] = (unsigned char) ((hk_lfr_le_cnt & 0xff00) >> 8);
    housekeeping_packet.hk_lfr_le_cnt[1] = (unsigned char)  (hk_lfr_le_cnt & 0x00ff);

Le compteur individuel est géré dans la fonction suivante:

void set_hk_lfr_ahb_correctable()   // CRITICITY L
{
    /** This function builds the error counter hk_lfr_ahb_correctable using the statistics provided
     * by the Cache Control Register (ASI 2, offset 0) and in the Register Protection Control Register (ASR16) on the
     * detected errors in the cache, in the integer unit and in the floating point unit.
     *
     * @param void
     *
     * @return void
     *
     * All errors are summed to set the value of the hk_lfr_ahb_correctable counter.
     *
    */

    unsigned int ahb_correctable;
    unsigned int instructionErrorCounter;
    unsigned int dataErrorCounter;
    unsigned int fprfErrorCounter;
    unsigned int iurfErrorCounter;

    CCR_getInstructionAndDataErrorCounters( &instructionErrorCounter, &dataErrorCounter);
    ASR16_get_FPRF_IURF_ErrorCounters( &fprfErrorCounter, &iurfErrorCounter);

    ahb_correctable = instructionErrorCounter
            + dataErrorCounter
            + fprfErrorCounter
            + iurfErrorCounter
            + housekeeping_packet.hk_lfr_ahb_correctable;

    housekeeping_packet.hk_lfr_ahb_correctable = (unsigned char) (ahb_correctable & 0xff);  // [1111 1111]
