Peak Detector Signal Amplitude.
Least significant byte of the receiver peak detector signal amplitude in mV. This register
should be read before register 16.
Analog Loss of Signal Hysteresis.
Analog
Read returns zero.
Analog Loss of Signal Threshold.
Upper two bits of the analog threshold value in mVppd.
