VDD Detection:
This pin selects if the V
(’0’) and reset pulses are generated on pin
RSTO or whether it is deactivated (’1’) and an
external reset has to be applied on pin RST.
Metallic Termination Input.
Input to evaluate Metallic Termination pulses.
Tie to ’1’ if not used.
Power Status (primary).
The pin status is passed to the overhead bit
’PS1’ in the U frame to indicate the status of the
primary power supply (’1’ = ok).
Power Status (secondary).
The pin status is passed to the overhead bit
’PS2’ in the U frame to indicate the status of the
secondary power supply (’1’ = ok).
Activation LED.
Indicates the activation status of U- and S-
transceiver. Can directly drive a LED (4 mA).
Test Pin 1.
Used for factory device test.
