Data Sheet
LDD
0: Clock generation after detection of any signal on the line in the power down state
1: No clock generation after detection of any signal on the line in the power down state
Note: If an interrupt is generated by the internal level detect circuitry, the microcontroller

DIS_TX
The transmitter of the transceiver can be disabled or enabled by setting DIS_TX. This
can be used to make the internal Loop_A transparent (DIS_TX = ’0’) or not
(DIS_TX = ’1’) (see chapter 2.3.10.1).
0: Transmitter is enabled
1: Transmitter is disabled
PDS
Defines the phase deviation of the transmitter (see chapter 2.3.5)
0: The phase deviation is two S-bits - 2 oscillator periods plus analog delay plus delay
1: The phase deviation is two S-bits - 4 oscillator periods plus analog delay plus delay

of the external circuitry
of the external circuitry
has to set this bit to ’0’ for an activation of the line interface.
