Display (C) If the operator has pressed the 2L key he gets display (C) likewise with the red line threshold displayed: N2 RED LINE=106.0%, together with the maximum reached after the last GENERAL RESET N2E1 = NO OVERSPEED The threshold 106.0% has not been reached
Display (D) If the operator has pressed the 3L key the EGT red line threshold is displayed: EGT1 RED LINE=910.0.C, together with the maximum reached after the last GENERAL RESET EGT1 MAX REACHED = 930. 0 .C
Display (E) If the operator has pressed the 3L key whereas the threshold for EGT has not been reached, then he gets the page (E) with the message EGT1 = NO OVERTEMP

G. DMC BITE Memory Features and Organization The BITE memory is a 2K-words non volatile EEPROM memory, which is physically implemented with the DMC common memory on the PFD DPU. The BITE memory can be accessed only by the PFD DPU, in order to avoid conflicts with other boards. The DMC BITE is divided into 4 zones: ZONE 1 : recording of EIS internal faults (DMCs, DUs, links) (flight, phases 2 to 9a ) ZONE 2 : recording of all the external faults (input buses) (flight, same conditions) ZONE 3 : recording of the internal fault, but without any flight leg history management (ground, phases 1, 9b, 10) more than 8+30 seconds, 9, 10). ZONE 4 : recording of all the failures, internal and external, in the ground trouble shooting mode. (Ref. Fig. 054)

3. Operation in the Normal Mode
____________________________
A. Transmission of Failure Information In the normal operational mode, i.e. with EFIS and ECAM images normally displayed on the DUs, the failures are automatically transmitted to the CFDIU as soon as they are detected, isolated and stored in the BITE memory, but only in the so-called flight phases, i.e. from 2 to 9a. On the ground, in phases 1, 9b and 10, only the EIS internal faults are recorded, but they are not transmitted. They can be read only in the menu mode, by a dump of the zone 3. However, the DMC still continues sending the failure messages of the last flight leg, i.e. those recorded in the flight phases of the last flight leg. The DMCs constantly know which failures they must record and in which BITE memory zone they must store them by decoding the command code transmitted by the CFDIU on its label 227. (Ref. Fig. 054)
