Description
Reserved
If set to 1 the threshold for BPSK demodulation is
dynamically adapted while reception.
Note: This setting is only valid in BPSK modes – otherwise it
is ignored
Defines strategy of signal processing regarding I and Q
channel
Both channels (I and Q) are used for signal processing
Use only I channel
Use only Q channel
Reserved
Use the strongest channel
Use the first channel
Reserved
This bit changes the Spike filter for the Phase shift detection
from order 5 to order 6 (default = order 6).
Resynchronization during the SOF for an equal correlation
value is done (default = activated).
The correlator is reset at a reset (default = activated).
Disables a special filter in BPSK mode. If set to 0, the
correlation of 0110 is filtered with the correlation of 1110 and
0111. Otherwise the demodulation is done using the
correlation with 0110
Data is received even before the first minimum at the SOF
(default: = deactivated).
Defines the MinLevel of the reception
Note: The MinLevel should be higher than the noise level in
the system
Note: Used for BPSK and Manchester with Subcarrier
Defines the MinLevel for the phase shift detector unit
Defines the length of the even period for the correlator for
Manchester subcarrier communication types
Defines how strong a signal must be to be interpreted as a
collision for Manchester subcarrier communication types.

No Collison
If set to 1 four samples are combined to one data. (average)
If set to one, the ADC-values are changed to a more
rectangular wave shape.
