ELMOS Test Modes
ELMOS Test Mode
deactivates all polarization
buffer outputs. This mode is
used for the TxU and TxL
leakage measurements to
avoid buffer pull-up and pull
down currents
ELMOS Test Mode
deactivates OVTxL shut off at
the LSD and disables the
FTL-timer. To reset this test
mode, the TEST-pin has to be
connected to GND again.
