Start Pulse Synchronization
If the start FFT window synchronization (start pulse is
locked) in the DTTV demodulator is correct, this location
is 1; otherwise, the start pulse is unlocked. The initial
condition for this bit is 1, locked.
Overall Chip Synchronization
If all aspects of the DTTV demodulator are synchronized,
this bit is 1. If this bit is 0, at least one unit is not locked.
The initial condition for this bit is 1, locked.
CSI Reliability Average
This register indicates the overall reliability of the carriers
by making an average (integer number) of the reliability
of each carrier.
CSI Reliability Peak
This register gives the integer number of carriers when
the value of the filtered Channel State Information
exceeds a given threshold. If more than 255 carriers
exceed this value, then 255 is returned.
