These bits are reserved.
COFDM Frame Synchronization
If the frame synchronization in the DTTV demodulator is
correct, this bit is 1 (ODFM frame is locked). If this bit is
0, the COFDM frame is unlocked. The initial condition for
this bit is 1, locked.
TPS Synchronization
If the BCH code in the TPS indicates that the TPS is
valid, this bit is 1 (TPS is locked). If this bit is 0, TPS is
unlocked. The initial condition for this bit is 1, locked.
AFC Synchronization
If the frequency synchronization in the DTTV
demodulator is correct, this bit is 1 (AFC locked);
otherwise, it is 0 (unlocked). The initial condition for this
bit is 1, locked.
Timing Synchronization
If the sampling frequency synchronization in the DTTV
demodulator is correct, this bit is 1 (VCXO is locked);
otherwise, it is unlocked. The initial condition for this bit
is 1, locked.
