TOO_MANY_LAMP_IGNITION_TRIES
If the ignition has failed LAMP_IGNITION_MAX_TRIES, g_too_many_ignition_tries vari-
able will be set, and the lamp will be switched off thanks to control_FBKIT.c file which
will switch off the ballast.

• The transition from LAMP_OFF to CONFIGURE_LAMP_PREHEAT is done
when the gv_pfc_state is set to PFC_CONTROL_LOOP in PFC_FBKIT.c file.
• The transition from the RUN_MODE state to the LAMP_OFF state is done in
the Control state machine in the case gv_lamp_preset_current is equal to 0.
• g_too_many_ignition_tries == 1 makes the ballast switch off in the control state
machine in control_FBKIT.c file.
