PSLCDA: Pre-Slicer disable
0: Pre-Slicer enable: only used in combination with TSI GAP Mode using
standard settings as below!
1: Pre-Slicer disable (default)
PSLCHYS: Pre-Slicer hysteresis
use 01b
PSLCTHR: Pre-Slicer disable threshold
use 10010 (0x12).
SDLORE: Source selection of ASK Noise Power status register
0: ASK Noise for SIGDET0/1
1: Signal for minimal usable FSK deviation
If enabled, the SIGDET low level can be read out from ASKNP register
SDSEL: Manual selection of SIGDET range
0: Disable(default) - SIGDET0/1 range selection factor automatically done;
depending on data rate
1: Enable - Use SIGDETSEL control to set the valid range
SDLOTHR: Signal Detector Threshold Low Level.
This threshold level is only valid if the FSK Noise detector selection in the
NDCONFIG register is set to “11b”
See application notes “How to choose an Application specific Signal Detection
Threshold for TDA523x based ASK Mode Applications” and “How to Choose an
Application Specific Signal- and Noise-Detection Threshold for TDA523x based FSK
Mode Applications” for specific procedure to determine this threshold by application.
